Zilvia, ohiodrifting, nicoclub and a lot on craigslist. But not in Columbus. I know of a few in dayton that are rust free and SR swapped.
I had a modded GTP for over 3 years and it was a great daily, but they are far from fun lol. I actually think my 240 has been more fun than my GTO, Mustang, and some of the other cars I've owned.
