SMG = ‘Serious Money Gone’ on your BMW.
The e46 M3 is actually one of the most reliable cars BMW has built in the last 10 years . . . Â unless you have the SMG option on your transmission of course. Â The first generation SMG (or Sequential Manual Gearbox) transmissions have not held up well over the long run and are starting to empty the pockets of their loyal owners. Â So if you are in the market for an e46 M3, stay clear of the SMG. Â If you currently have an SMG M3, this may be what you’re in for if you haven’t had the pleasure already.
