I just bought my first BMW. it is an 85' 318i. that is all i really know about it. i was wondering what the specs are on this model, as far as engine size etc. this car also needs some work (it was only a $500 car) three of the four windows need new motors, so i was told, and i desperatly need a new driver's seat. i have been able to find window motors on-line, but where can i find a replacement seat?
