I think sometimes I really wish I had, but when I'm busy wasting most of the cocky pricks in V8s, I'm definitely glad I did.
Seriously though, I think If I had the opportunity to have my car back the way it was stock, and have the 15-20 grand I've dumped into my car, wether its stereo stuff, motor stuff, or stuff for looks, or suspension, I'd probably rather a stock R and the moolah.
Guess I'll really never know......
Just remember, don't get too caried away, though I love mine like a child, and would be devistated if anything were to ever happen to it. It's jsut a car.
Later,
