Used Car Inspection Checklist
Never buy a used car without checking it first. Use this interactive checklist on your phone or print it out to spot hidden red flags before you buy.
Direct Answer
A thorough inspection involves checking fluid conditions, looking for hidden rust or accident damage, and ensuring the transmission shifts smoothly on a test drive.
Used Car Inspection Checklist Progress
Exterior & Underneath
Are the gaps between the hood, doors, and fenders even? Uneven gaps indicate previous accidents.
Look under the wheel wells, door bottoms, and the frame.
Are all four tires the same brand? Is the tread wear even?
Look under the car for fresh puddles of oil, coolant (green/pink), or transmission fluid (red).
Is there heavy black or blue smoke when starting the car?
Under the Hood (Engine Cold)
Pull the dipstick. Is the oil milky or frothy? (This indicates a blown head gasket).
Is the coolant level correct? Does it look like mud or have oil floating in it?
Are the rubber belts cracked or frayed? Are hoses soft and mushy?
Is the engine block covered in thick, wet oil sludge?
Interior & Electronics
Does it smell like mold or mildew? This can indicate flood damage or water leaks.
When you turn the key to 'ON' (without starting), do the Check Engine and Airbag lights illuminate, then turn off after starting?
Does it blow cold air within a minute? Does the heater get hot?
Do all windows roll up and down smoothly?
The Test Drive
Did the car start immediately without struggling or making rattling noises?
Does the automatic transmission clunk or hesitate when shifting gears?
Does the steering wheel shake or pull to one side when braking hard?
Does the car vibrate or wander at 65+ mph?
Paperwork & Final Checks
Is the seller's name actually on the title? Is it a Clean title (not Rebuilt/Salvage)?
Does the VIN on the dashboard match the VIN on the title document?
Does the owner have receipts for oil changes, timing belt replacements, etc.?
