My suggestion: don't bother. I agree with the BMW forums. Sell it over there, and get another '95 320i Coupe after you PCS.
I spent about $900 getting my '56 T-Bird modified to run on unleaded gas, and still remain as original as it was in January, '56, when it was assembled. The unleaded gas ate up the dual-diaphram fuel pumps almost as fast as I could replace them.
Altering a vehicles platform often causes too many additional problems.
One other thing - don't ever fall in love with a vehicle. Like'em, but don't love'em. Like wimmin - they ain't cheap!
