I beat the hell out of my 1989 Mazda RX7-GTUs. The first motor had 189,000 miles on it when I had it rebuilt. It was still running great, but I was going to have to replace cats every two years to get it to pass smog, so I had it rebuilt.

When I sold the car last Summer, it was 18 years old, the re-built motor (about 6 years old) had about 45k miles on it and was running like a top.

That 2nd gen RX-7 (non turbo) was the most reliable machine of any kind I've ever owned. I haven't owned the Boxster long enough to form an opinion about its reliability.
