A car imported from Germany or Japan after three years of ownership will usually have covered considerably more distance than its age suggests, and it will have been serviced under a different regime. That combination is not disqualifying, but it does change what you should be verifying.
Get the foreign service history translated
German and Japanese service records are detailed and useful, but they assume the reader knows the maintenance culture of the market. Ask for a full copy of the stamped records and have the intervals read against the car in question. Critically, establish whether the vehicle was serviced by a marque dealer. A vehicle serviced exclusively at independent garages has a very different expectation of life from one with a complete dealer network history.
Assume the clutch was replaced, then check
On a manual diesel, a dual-mass flywheel and clutch assembly is a two-thousand-pound repair. On these cars it is commonly done once, and it is usually done because the original reached the end of its life. Ask for the invoice. If it was replaced at 80,000 miles, the second assembly should be expected around 160,000; if it was replaced at 140,000, you have bought significant remaining life and should recognise it in the price.
Suspension components are the quiet casualty of distance
Rubber-bushed components wear predictably with mileage. On these vehicles that usually means control arm bushes, anti-roll bar links, ball joints and the rear strut mounts. Wear shows up as a knock over expansion joints rather than as a failed part. Inspect the underbody on a ramp and note any bushing that has separated from its casing.
Check for evidence of water and cooling system damage
Diesel cooling systems, especially on automatic transmissions, work hard in heavy traffic and heat. Expansion tanks and radiators crack from age and pressure rather than mileage. Look for fresh coolant residue on the lower radiator support, and confirm the expansion tank has not been replaced with a non-original part.
Water damage is a different issue. Check the carpet edges and the boot floor for staining and check the seat bases for dampness, particularly on vehicles from flood-prone regions.
Inspect the tyres as a mileage record
If the vehicle is fitted with nearly new tyres and the age stamp matches a recent change, note it; it may indicate work the seller wanted performed. If the tyres are original to the car, treat the tread depth as a rough odometer. Uneven wear across the tread again points to alignment.
Verify the import paperwork and modifications
Confirm the vehicle has a clear title with no salvage or flood brand, that the VIN on the car matches the import documents, and that any modifications are recorded. Modified suspension or exhausts on an imported car can affect both the inspection and the insurance.
Finally, ask for a pre-purchase inspection report for the specific vehicle and have it performed locally rather than at the seller's location, so the findings are not interpreted by whoever benefits from them. This is standard practice on an imported car, and any seller who objects is telling you something.
