Yeah I'm aware of the rebuild issue, but my understanding is they're a lot cheaper to rebuild than a piston engine anyway.
I've heard all sort of stories, from people rebuilding them every 20,000ks to people have clocked over 300,000km on their old rotary without an issue.
I understand they have their drawbacks, reliability and fuel consumption being two primary ones, but RX-7 itself is a phenomenal car. They rival Silvia's in weight and balance, yet can compete with the 2JZ in outright power. Plus they look and sound amazing. Damn, I sound like a fanboy already.
