I'll try to explain.

In the games, upon reaching a certain mileage, the power output of the car will start to decrease due to deterioration of the engine. As such, cars with high mileage are cheap, but also have a more deteriorated engine, which can be restored in "GT Auto" by selecting "Overhaul Engine" (only in the PS3 games, though, in the PS2 games you can only perform oil changes). Vice versa, low mileage cars, while slightly more expensive, have a less deteriorated engine, and as a result the power output is slightly higher.

However, while any car is subject to engine deterioration if driven long enough, the most prone to have a deteriorated engine are the Used Cars in GT4 and GT5 (primarily the road cars in the latter), due to their already high mileage.
