I have an 84 633csi I was told on www.ben liaws bmw site that mine was one of only 90 in the US .They may be able to tell you.GOOD LUCK I'm not a regular on this board, so please pardon me if this question has been covered before. How difficult is a 1988 or 1989 635csi (not an M6) with a 5 speed manual transmission to come by? Virtually every late-model 635 that I've seen is an automatic. Were manuals imported into the U.S. at that time? TIA-Robert
