Great to hear! On the contrary, i bought a car with just over 100k miles and a valve had gone; a reminder that you still have to keep an eye on things.

However, the worst car i've seen is a very low mileage one at JDR. The crank had broken where it had simply been started up and warmed up in the garage over a number of years. A very expensive fix which probably outweighed the appreciated value (and the fact the owner barely got to drive it).
