E46. It took me a long time to find this particular car....I hate to let it go, but have several other cars that I like better. It's an '06 ZCP car. Interlagos blue, grey leather, 6-spd, non moonroof(hard to find in an M3), and 37700 on the odo. Factory freak. It runs pretty good. I took my wife in her TBSS and her truck runs high 12's. I also put it on another M3 guy in houston who has an E46 with a HOB super charger setup. I was very pleased when I realized how well this car runs. Here's a few pics. It's a very hard color to capture on camera, especially when the clouds are coming in and out.With that price range you should definitely be able to find a good lbz/lmm truck, no doubt about it. My only recommendation is to keep looking over the classifieds here, auto trader, cars.com and craigslist and you'll have a rig in no time. Just don't jump in to it, there are plenty of them out there.
Also what year m3 do you have? I've had a soft spot for the e36's for years now :drink
