I used to work on Ferrari experience cars, each of which had done well over 100,000 track miles. One of the 355's lunched its gearbox, but they were all reliable at that mileage due to the maintenance plan. I know of one 360 with over 80,000 miles on it that is running 100 H.P of NOS and several other mods, regularly tracked, still on it's original engine and 'box with no issues. It appears that Ferrari is the only brand on the planet so mileage sensitive. Its a ridiculous concept. Some of the worst cars i have worked on have been low mileage garage queens.
