Personally I have found higher mileage cars tend to have been more reliable for me than low mileage ones. Provided they are well maintained they seem to have less problems. Not that I have masses of data, just personal experience with vehicles I've had.
Totally agree.... very low miles cars (of any type) suffer from all sorts of problems with things like wheels cylinders etc. Mark Baldwin told me the reason my Aero starter was jamming was because I was not using it enough
I agree to an extent.
I'd rather buy a well maintained car, with full service history that has been used; rather than a garage-queen that needs refreshing due to lack of use.
However, I also think there is a limited market for high mile Aeros. Few people will want to use the car daily and for most it will be a toy. Therefore, it is not unfair to believe that they will view an Aero with 12,000-miles per annum as too high for their liking and either expect a massive discount or just opt to buy one with 6,000 or less per annum.
