newer is better, but if you ever find a babied GSX I'd get the GSX. like what Schiedes says, the sky's the limit for these cars. Sometimes I want to get a 2g 97-99 GSX just because of the looks. I'm not a big subbie fan because we're rivals! lol. jk, but it seems that subarus are just much are harder to work on and all. here's a 2g i found on craigslist.
