My old Acura RSX
A few years ago I leased an Acura RSX. I believe it was 2002, the first year the model (a replacement of the venerable Integra) was available in the United States. It was a great car: speedy, responsive, nice turn radius, and decent looking. My girlfriend (at the time, now wife) and I really enjoyed it.
A few months after I got the car I saw a story in Import Tuner about a Wings West RSX demo car: it was awesome! I seriously wanted to repeat what they did, but (a) my car was a lease, and some of the mods would have broken the warranty agreements, and (b) there was a good amount of custom work there, done in California, and I lived in Boston at the time. So no go on that. Oh well :) It was still a great car.
