I'll second the vote for the 97 Trans-Am cause thats exactly what I have 🙂
But if you want a beemer, AT LEAST get a 325! Used 94's can be in that price range. I test drove the 318ti when it first came out, just to see what a $20k beemer was like...and it was dissapointing, kinda like a $20k Escort or something. So stay away from the 1.8 and get a 2.5!
