Keep looking for a 325is or 325i. This one just popped up tonight on SFBay Craigslist:
1987 BMW 325is E30 - $1000 (novato)
"I have for sale a 1987 BMW 325is. It has about 230k on it, but it runs fine. I have, within the past six months, replaced the water pump, power steering pump, steering rack and rear upper shock mounts. I also upgraded the suspension with H&R lowering springs, shocks and struts. All the work was done by an experienced BMW mechanic at Casey Motorsports. The car is complete and in running order. The only real issues with the car are a couple dents, both of which were hit and runs in a parking lot, not anything serious. It’s simpley cosmetic. I need to sell the car so that I can get something a bit more practical. I commute 40 to 80 miles a day to work and school so I’d like something that is better on gas. Feel free to call with any questions."

I bought my 87 325is with a blown head gasket for $550
Good hunting!
