I bought my Camaro in 03, and I have no intentions of ever getting rid of it. I see it as mostly centimental value, and I just love the car. Like you it will always be a work in progress, trying different things, it'll never be done. The Mazdaspeed Miata I recently bought could possibly turn into the same thing, but its too early to tell. I absolutly love the little car, and if I get another beater this year like I'm hoping the Miata will almost certainly become yet another toy I can't part with.
