Used Car Inspection Checklist

Complete pre-purchase inspection checklist covering all critical areas when buying a used car including documentation verification, mechanical inspection, test drive evaluation, and negotiation preparation.

1. Documentation & History

1Confirm the title / registration papers are genuine and match the seller's name
2Check for liens or legal encumbrances on the car
3Review vehicle history report (accidents, flood, salvage, recalls)
4Verify VIN (Vehicle Identification Number) on multiple parts (dash, door jamb, engine)
5Match odometer reading with service records and wear
6Examine maintenance & service records (oil changes, major repairs)
7Check for recall notices and whether they were addressed
8Ensure the owner's manual, warranty booklets are present
9Ask about previous ownership (how many owners, commercial use)
10Confirm insurance / emissions / safety inspection history (if applicable locally)

2. Exterior Body & Finishes

1Inspect for dents, dings, and scratches across all panels
2Look for rust spots, bubbling paint, or corrosion on edges and lower panels
3Check that body gaps, panel alignments are consistent (doors, hood, trunk)
4Look for signs of repainting / overspray / mismatched paint
5Examine doors, trunk, hood for smooth opening/closing and proper fit
6Inspect glass and windshield for cracks, chips, or pitting
7Test all exterior lighting (headlamps, tail, indicators, brake, fog)
8Check mirrors (side & rear) for cracks, looseness, proper adjustment
9Inspect wipers, washer nozzles, ensure they work and no leaks
10Check badges, trim, moldings for looseness or missing pieces

3. Wheels, Tires & Suspension

1Measure tread depth on all tires (including spare)
2Check for uneven wear patterns (could indicate alignment/suspension issues)
3Inspect sidewalls for cracks, bulges, or damage
4Confirm all tires are same size / load rating (or compatible)
5Assess rim / wheel condition (dents, bends, cracks)
6Test wheel lug nuts / torque / locking lug presence
7Push down each corner (bounce test) — the car should rebound once
8Inspect shocks, struts, springs for leaks, damage or sag
9Check ball joints, tie rods, bushings for play or wear
10Examine undercarriage / frame rails for rust, damage, signs of repair

4. Under the Hood / Engine Compartment

1Check engine oil level and quality (clean, not milky or sludgy)
2Inspect coolant / radiator fluid for level, color, and leaks
3Examine belts and hoses for cracks, softness, wear
4Look for any fluid leaks (oil, coolant, power steering, etc.)
5Inspect the battery (age, terminals, corrosion)
6Check air filter, intake system, ducting, hoses
7Inspect engine mounts for crack or looseness
8Check spark plugs, wires (if accessible) for condition
9Inspect radiator, cooling fins, fan, shrouds for damage
10Smell for burnt odors, smoke or coolant smell when engine runs

5. Transmission & Drivetrain

1For automatic, inspect transmission fluid (color, smell, level)
2For manual, test clutch pedal for free play, smooth engagement
3Check gear shifts (automatic/manual) — smooth transitions, no slipping
4Listen for gear noise, whining, jerks during shifting
5Inspect drive axles / CV joints for boots, leaks or damage
6Test 4WD / AWD / differential (if equipped) operations
7Check for transmission leaks around seals and pan
8Inspect universal joints / driveshaft for play/vibration
9Assess the differential fluid (if accessible)
10During test drive, verify reverse gear, uphill starts, torque delivery

6. Brakes & Steering

1Check brake pads / shoes thickness and even wear
2Inspect rotors / drums for grooves, warping, rust
3Check brake fluid level and clarity (not dark or muddy)
4Test emergency / parking brake for holding power
5During test drive, evaluate straight-line braking (no pull)
6Check for vibration or pulsation in pedal or steering wheel during braking
7Inspect brake lines, hoses for cracks, leaks or bulging
8Confirm power steering fluid, rack & pinion, gear box condition
9Test steering response (no looseness or play)
10Check for steering noise (clunks, clicking), binding at turns

7. Electrical / Electronics / Features

1Test all dashboard warning lights at startup (ABS, check engine, airbags)
2Ensure gauges (fuel, temp, oil, volt) operate correctly
3Try radio, speakers, infotainment, Bluetooth connectivity
4Check climate control / AC / heater blowing cold / hot air promptly
5Test power windows, power locks, mirrors, central lock
6Check sunroof / moonroof for operation and seal integrity
7Test interior lights, map lights, dome lights
8Verify USB / charging ports / 12V outlets
9Test rear camera, parking sensors, backup assist (if equipped)
10Check alarm / immobilizer / key fob functions properly

8. Interior & Comfort

1Inspect seats / upholstery for tears, stains, sagging
2Check for water stains, dampness, mildew odor (possible leak)
3Test seat adjustments (manual/electric)
4Inspect headliner, trim, door panels for damage or looseness
5Check carpets / mats for wear or moisture
6Test all seatbelts for locking, retraction, condition
7Inspect door seals, weather stripping for cracks or gaps
8Test glove box, console, storage compartments
9Verify sun visors, mirror covers, overhead console condition
10Listen for rattles, squeaks in interior when shaking doors etc

9. Test Drive & Performance

1Cold start: engine should start easily, idle smoothly
2Accelerate from low to highway speed — no hesitation or lag
3Cruise at higher speed — check stability, vibrations, noise
4Brake firmly — should feel smooth, straight, no pulsing
5Turn corners / curves — check for pulling, uneven behavior
6Listen for suspension noises over bumps or rough roads
7Shift through all gears (manual/auto) and test reverse
8Test AC / heater during drive, watch temp gauge for overheating
9Check for vibrations in steering wheel, seats, or body
10After the drive, re-check under hood and undercarriage for new leaks

10. Final Review & Negotiation

1Summarize all defects, repairs needed, cost estimates
2Use findings to negotiate price reduction or repair inclusion
3Confirm warranty / "as is" status in writing
4Ensure all keys / remotes / spare keys are included
5Get a written agreement covering the transaction details
6Check insurance / registration cost / taxes for that vehicle
