depends on how the cars been driven.

cars with low miles can be for many reasons.

If its been a town car then its quite possible for it to be daily driven, never warmed up properly, always start stop etc. And then youd expect problems as its had a harsh life.

However a low miles car could be something driven as a second car or not driven often and hence genuinely in good condition.

High mileage motorway munchers can be in good nick for the mileage as motorway driving is low load on most of the componants.
