I think it's cool to see people with nice cars posting on TR. Usually people with 2000 dollar DSMs and Civics chase them away before they get addicted and/or develop a hard enough skin to stand up to forum flames. It's mostly jealousy- look around at cars in peoples' profiles and you can tell that the majority of people here are young kids making way less than 30k a year. It seems that when these kids grow up and start making real money they either get out of cars entirely or just lose interest in posting. I'm sure a lot of the broke young kids who used to post 4 or 5 years ago are much better off now but just lost interest along the way.
The only thing I'm jealous of is your road racing. So awesome, but so far outside my college-student budget. At least I got rid of my over-modified DSM- I could never have made that thing road course bulletproof on my budget. I'm looking at getting a stock 240sx or MR2- even if I'm very slow, at least I should be able to track the car without my mods catching up with me.
