Ah.... what makes you think that? Engine life has been discussed, and it's never a simple formula. You could have bad luck happen like snap the cam belt, and the engine is gone.
Or if you're sitting up at the limiter all day doing burnouts/drifting, it won't last as long as a modded engine that's driven easily.
As I always believe, buy a good car, look after the engine, treat it well, and it'll look after you. By treating it well, i don't mean drive like a granny. I mean service it with good oil, and frequently. Have it tuned well. Drive hard, but don't sit at the limiter. I fang my car hard, but i take these above factors into account.
