1. Service records first, car second
On a European car, maintenance history is worth more than a clean exterior. Oil changes on schedule, cooling system work, and the model's known weak points already addressed are what separate a good buy from a gamble. No records is not automatically a no, but it moves everything else on this list from nice-to-do to mandatory.
2. Cold start it yourself
Ask the seller not to run the car before you arrive, then listen to the first ten seconds. Rattles, clatter, smoke and rough running on cold start reveal timing chain wear, valvetrain problems and oil consumption that a warmed-up engine hides. A seller who insists on warming it up first is answering your question in a different way.
3. Scan every module, not just the engine light
A blank dashboard means nothing. Fault codes can be cleared minutes before you arrive, and European cars store history in dozens of modules that a basic parts-store scanner never reads. A proper diagnostic scan shows stored faults, how long ago they set, and mismatches that suggest the car is hiding something.
4. Look underneath, not just under the hood
Oil leaks, coolant residue, torn axle boots, rusty subframes and fresh undercoating in suspicious places are all visible from below and invisible from above. This is half the value of putting a car on a lift before buying it.
5. Drive it like you will actually drive it
Highway speed, full-throttle onramp, hard stop, tight parking-lot turns. Vibrations, pulls, clunks, hesitation and transmission flare each point somewhere specific. Five gentle minutes around the block tells you almost nothing.
6. Price the known issues into the offer
Every model on our blog has a known list: chains, water pumps, carbon, mounts, air suspension. If the work is not documented, it is not done, and the cost belongs in your negotiation, not in your first year of ownership as a surprise.
7. Get a pre-purchase inspection
Everything above, done properly, on a lift, with dealer-grade diagnostics, by someone whose only interest is telling you the truth. An inspection costs a fraction of the cheapest repair it can save you from, and sellers who refuse to allow one are telling you the ending in advance.
