A VIN check tells you a lot about a car's paper trail — accidents, mileage, ownership, recalls. It won't tell you everything, though. Some problems only show up when you're standing next to the actual vehicle. Here's what to look for.
1. Mismatched panel gaps or paint
Stand at the back of the car and look down each side. Panels that don't line up evenly, or paint that looks slightly off in color or texture on one panel, usually mean a repair — sometimes a minor one, sometimes evidence of a bigger accident than the seller mentioned.
2. Fresh undercoating or a very clean engine bay
A pristine, freshly cleaned engine bay on an older car isn't always innocent — it can be used to hide oil leaks or rust. Ask when it was last cleaned and why.
3. Uneven tyre wear
Tyres that are worn unevenly, or worn differently from side to side, can point to alignment issues, suspension problems, or worse.
4. Fluid leaks or stains
Check under the car after it's been parked for a few minutes. Spots of oil, coolant, or transmission fluid are worth asking about directly.
5. A VIN plate that looks tampered with
Compare the VIN on the dashboard plate, the door frame, and the registration document. They should all match exactly. Scratches, re-stamping, or a plate that looks like it's been swapped are serious red flags.
6. A seller who won't allow an inspection or test drive
This is the simplest one. A legitimate seller has nothing to lose by letting you take the car to an independent mechanic before you commit.
7. Pressure to decide immediately
"Someone else is coming to see it this afternoon" is a common tactic to stop you from doing your due diligence. A car that's actually right for you will still be right for you tomorrow.
None of these replace a proper mechanical inspection — but combined with a full VIN history report, they go a long way toward avoiding an expensive mistake.
