You found a car, the seller is waiting, and you have five minutes before the small talk turns into a sale. That’s enough time to catch the worst problems if you spend it well. Here is exactly what to check, minute by minute, with no tools and no jargon, just the moves that stop the expensive mistakes before they happen.

Minute 1: Run the Report

Before you look at a single panel, scan the car with Scan VIN. Type the plate or 17-digit VIN into one field on your phone and read the result. The report opens with a Scan VIN Score from 1 to 10 and flags the deal-breakers fast: write-off or scrap status, mileage rollback, outstanding finance, theft status, accident records, and flood exposure.

If any of those show up, you’re done. Walk away and keep your money, no inspection can fix a car that shouldn’t be sold in the first place. If it’s clean, spend the next four minutes confirming the car matches its good history.

Minute 2: Walk Around

Look down each side of the car at a low angle. Ripples in the bodywork or paint that doesn’t quite match between panels point to past crash repairs the report may not capture in full. Check that all four tyres wear evenly across their width: uneven wear means alignment or suspension trouble, and a fresh tyre on just one corner can be hiding accident damage underneath.

Minute 3: Open Everything

Pop the bonnet, open the boot, and lift the boot carpet. You’re looking for damp, rust, or a suspiciously new-looking section in an otherwise older engine bay, all signs of repair or water damage. Then sit inside and breathe in. A musty or chemical smell often means a past flood, which you can cross-check against the flood data in your report.

While the bonnet is up, glance at the oil cap and the coolant. A creamy residue under the cap can signal head gasket trouble, the kind of fault that turns a bargain into a bill.

Minute 4: Cold Start and Lights

Start the engine from cold and watch the exhaust. Blue smoke means the engine is burning oil; white smoke that lingers can point to a head gasket problem; a hard, reluctant start is worth questioning. At the same time, check that every warning light on the dashboard comes on and then goes out, a light that stays lit, or one that never lit at all, is a problem someone may be hiding.

Minute 5: The Documents

Match the VIN stamped on the car to the VIN on the registration document and to the VIN on your Scan VIN report. All three should agree. Then check the seller’s name matches the registration. A VIN that doesn’t line up, or a seller who isn’t the registered keeper, can point to a cloned or stolen car. Any mismatch here means stop, no matter how good the car looks.

Bonus: Use the Report as Your Negotiating Notes

The five-minute checklist doesn’t just protect you from disasters, it hands you reasons to pay less. The Scan VIN report flags things like a service gap, an inspection coming due, or emissions data that means higher running costs, and each of those is a fair, factual basis for a lower offer. Quote the cost of the upcoming work, not your feelings about the car, and the seller has little room to argue.

Because the report comes with a downloadable PDF, you can keep it open on your phone during the haggle and point to the exact line you’re referring to. It’s much harder for a seller to brush off a documented record than a vague “I read somewhere that…”

Quick, But It Works

Five honest minutes filter out the vast majority of disasters: the rollbacks, the write-offs, the finance traps, the flood cars. None of it requires expertise, only the discipline to do it every single time before money changes hands. Make minute one, the scan, non-negotiable, and the rest falls into place. Next time you’re standing in front of a car you like, start the clock and run the report first.
