Finally found some good info, , and in my mind my options seem to be a '85 4door 323i 150hp..., 87-89 2Door 320i 130hp..., '89 320is 190hp

but im assuming this is either expensive or rare or both.... then theres 85-89 2or4/door 325i 170hp...
What do you guyz recondmend outta this list, keep in mind Price/Availability/Tune-ability/Performance.... etc. Thx alot guyz, just so many options im kinda stump as to where to start.
PS my main thoughts are on the 323i vs the 2/Door 320i......
