Here's THREE of my cars I bought while I was in med school:
This Audi 90 will stay stock for the most part since it's my daily driver. The only thing I've changed out was the entire stereo. Pics will come later, but I have an Alpine MP3 deck, MB Quart components in the front and rear, JL amp and a 12" JL W7 sub for a little bass. I'm planning on adding a cone filter and maybe an after market exhaust.

This Mazda RX-7 is my weekend car, when I actually find time to drive. This ones is meant for performance. Other than the 17" wheels, she's stock on the outside. I installed a small red neon light behind the front plate. It adds a little touch of creativity and matches the red leather interior. On the inside, I've got a full straight exhaust with a Blitz cat-back exhaust and no cats. Pettit reprogrammed the ECU and RX7 Fashion made the intake box and SMIC. The rubber vaccum hoses were replaced with silicone ones and the stock BOV was replaced with a Blitz SS BOV. There's a good chance I'll sell it, so if anyone's interested, let me know. I've never taken it to the track or strip and it has less than 82K on the clock. dzungh@hotmail.com

Here is a pic of the RX-7 the day I bought it. The wheels were stock, but they still looked nice.

This ugly looking Audi 4000s will soon undergo a transformation to a not-so-ugly Audi 4000s. I need to do a little body work before I get it painted to S4 blue. It'll probably become my autocrossing car since I won't be too pissed it I wreck it. I only paid $400 for it. Not too shabby.
Well...I'll update with more pics later.
