Can anyone provide production figures for E30 M-technik? I own a 1991 E30 M-Technik convertible (red with black M-tech interior) and am wondering how much a collector's item I should consider it, i.e., I also have a 1992 E30 non-m-tech convertible and I'm thinking I should be keeping miles off the M-tech. I think I understand that in 1991 and 1992 there were around 200 made one year and only 14 the other, any idea? Sources? Also, is there a source that notes the differences between the M-tech and standard 325i? There appear to be some positive performance enhancements, but I simply don't know what they are. Thanks.
