... and ask a lot of sensible questions.
We all know odo reading is at best only a very rough clue about the condition of the drive train (engine, gearbox, etc). It's not only possible but frequently the case that a car with 100 000km of long distance open road kilometers has an engine+gearbox in far better nick than many a car with 25 000km of stop-go city driving over short distances. By far the roughest thing for an engine in normal use is the time from cold start to full running temp, and that can easily take 10-15km, depending on car and conditions. Doing 25 000 km in short-trip stop-go city driving is very, very heavy on mechanical parts. Of course oil and temps are critical too.
