Used Family Car Inspection Checklist: 50 Points to Check Before You Buy

Start outside the car in full daylight — never inspect a used car in a dimly lit garage or at night. Walk slowly around the entire vehicle before touching anything.

1. Panel gaps — crouch down and sight along the doors, hood, and fenders. The gaps between panels should be even and consistent on both sides. Uneven gaps or a gap that widens toward one end almost always indicate accident repair where a panel was replaced or the frame was straightened.

2. Paint overspray — open every door and inspect the jambs, the rubber door seals, and the bolt heads on hinges and the hood. Original factory paint does not reach these surfaces; repainted panels do. Overspray on rubber seals or paint-covered bolt heads confirm that section of the car was repainted after a collision.

3. Rust on door sills and wheel arches — get low and look at the bottom edge of each door and the inner lip of the wheel arches. Surface rust on exposed metal edges is common on older cars but deep pitting, holes, or bubbling paint underneath means structural rust that is expensive to repair properly.

4. Windshield and glass — check the windshield for cracks, chips, and delamination (a white haze at the edges). A cracked windshield in the Philippines costs ₱3,000 to ₱15,000 to replace depending on the model. Check rear and side glass for chips or scratches from incorrect cleaning.

5. All exterior lights — ask the seller to turn on headlights, taillights, hazard lights, turn signals, reverse lights, and brake lights while you walk around confirming each one works. A dead bulb is cheap to fix but suggests the seller has not been maintaining small items.

6. Tire tread depth — press a 1-peso coin into the tread grooves at three points across the width of each tire. The coin's milled edge should disappear into the groove; if you can see the full edge, the tread is worn below safe limits. Check all four tires plus the spare.

7. Tire age — look at the sidewall of each tire for a four-digit DOT date code stamped in an oval (e.g., 2319 means the 23rd week of 2019). Tires older than five years should be replaced regardless of tread depth because the rubber compounds degrade and increase blowout risk.

8. Spare tire, jack, and tools — open the boot or under-floor compartment. Confirm the spare is inflated and the correct size, the jack is present, and the lug wrench is there. A missing spare or flat spare tire tells you the car has had at least one puncture the seller did not bother to address.

9. Hood alignment and latch — open and close the hood and check that it sits flush with the fenders on both sides. A hood that sits high on one side or requires force to latch suggests the front end has been in a collision.

10. Door hinges — open each door fully and lift the door slightly while it is open. There should be minimal play in the hinge. Sagging doors that drop when opened indicate worn hinges from heavy use or damage and can be expensive to repair on older models.

Flood damage is the single most common hidden problem in second-hand cars sold in the Philippines. Metro Manila, Pampanga, Bulacan, and Cavite flood regularly during typhoon season, and thousands of flood-damaged vehicles enter the second-hand market each year after being cleaned and detailed to hide the evidence. A flooded car suffers long-term electrical failure, accelerated rust, and engine damage that may not fully surface for months after purchase. Never skip this section.

11. Waterline marks — open each door and look inside the door jamb from floor level to window level. A distinct tide line — a faint horizontal discolouration or residue — at any consistent height across the car is the clearest sign of flooding. Also check inside the boot lid and the firewall in the engine bay.

12. Silt deposits in crevices — flood water carries fine sediment that settles in hidden areas. Use a flashlight and look inside the air vents, in the corners of the dashboard, in seatbelt retractor housings, and along the base of the B-pillar. Dried silt that a detailer missed is a reliable indicator.

13. Floor pan rust — lift every floor mat, including the boot mat. Press on the carpet and feel for dampness or stiffness. Look for rust spots, brown staining, or bubbled paint on the metal floor pan. Original carpet that has been soaked and dried takes on a rigid, cardboard-like texture that is distinctive.

14. Electrical connector corrosion — find the main fuse box (usually under the dashboard on the driver's side) and look at the wire harness connectors. Green or white corrosion on the metal pins of any connector means the area was submerged. This causes intermittent electrical faults that are extremely difficult and expensive to diagnose.

15. Musty or mildew smell — sit inside the car with the windows up for two minutes before starting the engine. A flood car retains a musty, earthy, or mildew smell in the upholstery and carpet padding even after professional cleaning and deodorizing. If the car smells strongly of air freshener or chemical cleaner, ask why.

16. Seat rail rust — push each front seat as far back as it will go and look at the metal tracks on the floor. Seat rails are one of the first places to rust in a flooded vehicle because they are near the floor and often overlooked during cleaning.

17. Under-dashboard wiring — crouch outside the driver's door and look up under the dashboard with a flashlight. Look for wire harnesses with dried mud residue on the insulation or green corrosion on any of the multi-pin connectors. Even minor corrosion here can cause years of electrical problems.

18. Spare tire well — the spare tire well sits lower than the rest of the boot floor and collects standing water during a flood. Lift the boot floor completely and look for a rust ring or waterline stain around the inside of the spare tire recess.

19. Engine bay firewall — the firewall is the metal panel that separates the engine from the passenger cabin. Look at the insulation foam glued to the lower firewall for dried silt, discolouration, or a distinct horizontal line where water rose to. Clean firewalls in old cars usually have at least some grease and grime; a suspiciously clean lower firewall may have been recently washed.

20. ECU and underdash computer modules — on many modern cars, control modules for the airbag system, ABS, and transmission are mounted under the seats or under the dashboard close to floor level. Ask the seller where the main ECU is located. Flood damage to any of these modules causes failures that can cost ₱20,000 to ₱80,000 or more to replace with a genuine unit.

Open the hood and let the car sit for a few minutes after any test drive before inspecting — a hot engine makes oil leaks harder to distinguish from normal heat shimmer and can cause burns. Ideally inspect a cold engine for the most accurate read.

21. Engine oil condition — pull the dipstick, wipe it, dip it again, and examine the oil. It should be amber to dark brown and leave a clean film. Milky, creamy, or frothy oil means coolant is mixing with the oil — a blown head gasket or cracked block that requires a major engine repair.

22. Coolant color and level — open the overflow reservoir (not the radiator cap on a hot engine). Coolant should be green, blue, or orange depending on the brand. Rusty brown or black coolant means it has never been changed and the cooling system has internal corrosion. Low coolant with no visible leak suggests a slow head gasket leak.

23. Oil leaks — look at the bottom of the engine, the valve cover gasket at the top, the oil pan at the bottom, and around the rear of the engine where it meets the transmission. Wet, black, oily staining in any of these areas means an active leak. Minor seep is common on high-mileage engines; heavy leaks indicate deferred maintenance.

24. Timing belt or chain status — ask the seller when the timing belt was last replaced (for belt-driven engines like most Honda and older Toyota). A timing belt failure destroys the engine. If the seller cannot produce a service record showing replacement within the manufacturer's recommended interval, budget for replacement immediately.

25. Battery condition and age — locate the battery and find the date stamp (most Philippine batteries have a month-year sticker). A battery over three years old in Philippine heat will need replacement soon. Look for corrosion on the terminals — white or blue powder buildup that has not been cleaned means the car has sat unused or the charging system is irregular.

26. Radiator and hoses — look at the radiator for green crystalline deposits around the cap and at hose connections; these are dried coolant leak residue. Squeeze each radiator hose — they should feel firm and slightly elastic, not rock-hard (brittle, about to crack) or mushy (deteriorated internally). Check the fan shroud for damage.

27. Air filter condition — locate the air filter housing and open it. A heavily clogged, black air filter means the owner has been skipping basic scheduled maintenance. If the cheapest serviceable item on the engine has been neglected, more expensive items almost certainly have been too.

28. Brake fluid reservoir — the brake fluid reservoir is usually a small translucent bottle near the firewall on the driver's side. The level should be between Min and Max. Very dark, almost black fluid means it has absorbed moisture over years without being changed — a safety concern that also indicates overall maintenance neglect.

29. Brake lines — get underneath the car and look at the steel brake lines that run from front to rear along the underfloor. Surface rust on the exterior is normal. What you are looking for is pitting, holes, or lines that have been repaired with rubber tubing and clamps — these are active safety hazards.

30. CV boots and exhaust — look at the rubber boots covering the constant velocity joints on the front axles. Cracked, split, or missing boots with grease sprayed around the joint area mean the CV joint has been running without lubrication and may need replacement. While underneath, check the exhaust for holes, rust perforations, or patchwork repairs that indicate a system near the end of its life.

Start the engine and let it idle throughout this section so you can test all electrical systems under normal operating conditions.

31. Air conditioning performance — close all windows and set the AC to maximum cold and maximum fan. After five minutes, hold a thermometer or your hand flat in front of the centre vent. A properly functioning PH car AC should blow at 8 to 12 degrees Celsius. Anything above 15 degrees means the system needs a regas at minimum and possibly a compressor or condenser repair.

32. All power windows — test each window independently from both the driver's master switch and the individual door switch. Slow or jerky operation means the window motor or regulator is wearing out. A window that works from one switch but not the other usually has a faulty door switch, which is cheap to fix.

33. Central locking — test all four door locks from the remote fob, from the driver's door button, and from each individual door button. Any door that does not lock or unlock properly needs actuator replacement. Also confirm the boot or tailgate lock works.

34. Instrument cluster — watch the instrument cluster during startup. All warning lights (engine, battery, oil, ABS, SRS/airbag, TPMS) should illuminate briefly as part of the startup self-check then go out within ten seconds of the engine running. Any warning light that stays on is reporting an active fault in that system.

35. Gauges — confirm the speedometer, tachometer, fuel gauge, and temperature gauge all respond correctly. An odometer that shows suspiciously low mileage on a car with worn pedal rubbers, a worn steering wheel, and worn seat bolsters is likely to have been tampered with.

36. Seat condition and adjustment — sit in each seat. Front seats should move freely on their rails and lock solidly in position. Lumbar support and height adjustment (where fitted) should work. Check for seat cushion sagging (foam has broken down from heavy use) and inspect seat fabric or leather for tears, burns, and staining that indicates the car's real history.

37. All seatbelts — pull each seatbelt sharply — the inertia reel should lock immediately and resist further pulling. Release and let it retract fully. Seatbelts that will not retract, lock too slowly, or have frayed webbing must be replaced before the car is used. Check that every buckle latches and releases cleanly.

38. SRS airbag system — the SRS warning light should illuminate at startup and then go out. A light that stays on means the airbag system has a stored fault and the airbags may not deploy in a collision. Ask specifically whether the car has ever had airbags deployed — deployed bags in a repaired car may have been replaced with non-functional dummy units to pass visual inspection.

39. Wipers and horn — test both front and rear wipers at all speeds. Confirm the washer fluid sprays correctly. Test the horn — a weak or non-functional horn is a safety issue and a simple indicator of electrical neglect. Replace worn wiper blades before the first rainy season.

40. Dashboard and trim condition — look critically at the dashboard for sun cracking, warping, or repaired cracks. Missing trim pieces, broken center console latches, and rattling interior panels are cosmetic issues but tell you how the previous owner treated the car. A seller who neglected visible interior maintenance almost certainly neglected invisible mechanical maintenance too.

Request at least a 15-minute test drive on a mix of slow city roads and a faster stretch where you can reach 80 km/h. Never accept a short idle test as a substitute for an actual drive. Bring this checklist and take notes while a companion drives so you can observe without distraction.

41. Cold start behavior — if possible, arrive early and ask the seller not to warm up the car before you get there. Start the engine cold and listen for the first 60 seconds. Light ticking that fades quickly is normal as oil pressure builds. Persistent knocking, clattering, or a cloud of white or blue smoke that does not clear within 30 seconds indicates serious engine wear or a coolant leak into the combustion chamber.

42. Braking performance — at around 40 km/h on a clear road, press the brake pedal firmly in a controlled stop. The car should stop in a straight line with no pulling to either side and no pulsing through the pedal. A pulsing pedal means warped brake rotors. Pulling to one side indicates a seized caliper or uneven pad wear.

43. Steering feel — drive at 40 km/h on a straight road and lightly hold the wheel. The car should track straight with minimal correction needed. Looseness, vagueness, or a clunking sound when turning suggests worn tie rod ends, ball joints, or a failing power steering pump. The steering wheel should return naturally to center after a turn.

44. Automatic transmission shifts — accelerate gradually from a stop to 60 km/h and pay attention to gear changes. In a healthy automatic, shifts should be smooth and almost imperceptible. Harsh jolts, hesitation before gear engagement, or slipping where the engine revs rise but the car does not accelerate suggests a transmission that will need rebuilding.

45. Manual transmission and clutch — in a manual car, test every gear including reverse. All gears should engage without grinding or force. The clutch engagement point should be consistent and not at the very top of the pedal travel (which indicates the clutch disc is nearly worn). A shuddering or slipping clutch under hard acceleration means clutch replacement is imminent.

46. Suspension over bumps — find a speed bump and roll over it slowly in a straight line. Each wheel should produce at most a single, solid thud. Multiple rattles, continued bouncing, or a metallic clank from any corner indicates worn shock absorbers, struts, or suspension bushings that need replacement.

47. Engine noise under load — accelerate from 40 to 80 km/h and hold at 80 for 30 seconds. Listen for detonation (a pinging or rattling sound under load), misfiring (a rhythmic stumble or hesitation), or unusual vibrations through the floor. These symptoms under load often do not appear at idle and are the most commonly missed engine issues.

48. OR/CR and VIN verification — after the test drive, examine the Official Receipt (OR) and Certificate of Registration (CR) carefully. The engine number on the CR must match the number physically stamped on the engine block. The chassis number on the CR must match the number stamped on the firewall or door pillar. Mismatched numbers are a serious legal issue and may indicate the car was involved in a carnapping case.

49. LTO registration status and arrears — verify the car is registered and the registration is current. Ask to see the latest registration renewal receipt. Unpaid registration arrears, stickers from previous years without renewal, and missing OR/CR are all problems that legally transfer to the new owner at purchase. Check the LTO portal or have a fixer verify the plate status before signing anything.

50. Encumbrance and mortgage check — a chattel mortgage is a loan secured against the vehicle. If the seller financed the purchase and has not fully paid, the bank still has a legal claim on the car even after you buy it. Request a certificate of no encumbrance from the LTO or use a car history verification service before paying. Also check if the car has any pending cases by searching the plate number — some buyers use Facebook groups or Carousell listings to flag carnapped plates.
