i'm going to sell my 325e because i want an e30 with a beefier engine. Of course, the only options are that of a later model 318is, 325is and the m3. I scratched out the m3 because the price of that is a little bit higher, which pushes it out of my budget. So in comparison, the pros and cons of 318is vs. the pros and cons of a 325is??? Correct me if i'm wrong, but the 318is = 4 cylinder, 325is= 6 cylinder?? That's all i know as of now. If you guys can, out of your own knowledge please enlighten me on these two beautiful cars.
