On these expensive cars (meaning worth the cost of maintaining them properly) with fuel injected engines (so perfectly lean mixtures) and unleaded fuel, there is no reason why they won't go forever.

Even if the engine does go, by the time it goes it should be pretty easy to find a replacement for a good price.

I can imagine that some of these cars will see 500,000 or 1,000,000 miles.
