You don't see a Rolls Royce or similar being pushed beyond its limits nearly as hard as the mass produced. Some of those mass produced will equal them if handled the same.<quoted text>
It depends. The Rolls Royce is theoretically the most reliable, but when it does break down, its an arm and a leg to fix. It may be the most reliable but certainly not the most maintainable. The most maintainable cars would probably be the japanese cars. They don't break down often, but probably do breakdown more often than a Rolls Royce. But they are more maintainable because when they do breakdown, they are not expensive to fix.
That's the key factors. A car must not break down often, and when it does, it must not be expensive to fix.
Rolls get loving attention, Toyotas get beat up.
