I know of a 1996 318ti ///M, which indicates "motorsport". I guess that means the 318 gets a bit of suspension change, and the cool sport seats. I like the seats: they're similar to the Vader seats in a real ///M3. The car has ///M badges on the door bumper strips. The Edmunds.com price on this car, assuming 45K miles, is about 15.5 KBucks. Oh yeah, the 318sa probably indicates sport/automatic.
