The age old phrase "buy on condition" is the best advice, i'm not saying don't look at the odometer but don't make a big deal of it.

Two personal recent examples from me;
-I searched for ages to buy an M5, and I always had this stupid taboo about buying cars with more than 100k miles on it, then after researching you find that a car with say 70-80k miles might need a new clutch, brakes, suspension and so on, where a car with 100k miles might already have had all thae expensive shit done, so don't get hung up on the number of miles. Outcome, i bought one with 99kk miles and it's never missed a beat, brilliant car!

Also just took delivery of an E36 328i, has 153k on the clock, the car has no stone chips on it, and runs like a clock, it has been meticulously maintained, i forget when i drive it how many miles it's done until i look at the odometer. It's a convertible and came from south england so drier weather and has likely been garagaed most of its life. Also if you buy a high mileage car, my preferance is to get one which has been owned from new by the present or very recent owner, you usually find its had all the proper servicing and wanted for nothing.

Bottom line is don't let the milage bother you (within reason), it's something that i moaned about for years and realised it's a load of shit.
