If you're going to buy a 3K, get the VR4. (Without a doubt) Unless, of course, you want reliability (The SL) without some fun. (No offense to TT'less people) The VR4 is a bitch to own though. A full gas tank, for me, costs around $35-40. (That's with 94) So far, I haven't had any MAJOR problems. My CEL is currently on which really pisses me off. The car only has 14K miles too, haha.
As far as money being spent, I'm starting to get into the mod scene. I bought a testpipe (only $40) and Pocketlogger. I actually just bought the pocketlogger software today ($175) and palm pilot ($70). I'll be buying more mods as the nicer weather comes out.
Watch out though, the VR4 can give you some problems if not taken care of properly.
Please remember not to rush to buy one of these cars. It took me two years to find the perfect one. Good things come to those who wait. Good luck!
EDIT - I've spent around $26,000 on the car and everything else all together.
