Post anything e12 related. Maybe this could be an interesting sticky thread for anyone wanting to know about these cars? This my modified 1976 528. It has the same engine and gearbox as a 1980 635CSi. The car has factory a/c and electric mirrors, also came with a blue cushion first aid kit. 100,000 miles. Bought the 3,453cc engine block from BMW when they were still available. The ZF 3HP automatic, I had a 2nd hand casing, and fitted new internals back in 1996. Car has the original 3.64 final drive ratio. Have upgraded the a/c with parallel flow condenser, and Sanden SD 508 compressor, refrig capacity is now 1.2 kg.
