According to my BMW NA parts number publication. The car was built for the 1986 model year. The "G" is the code for 1986. For all 1987 and later models the NHTSA requires that the VIN number be marked on specific parts of the car when manufactured. A label is placed on the engine, transmission, frt bumper, rr bumper, hood, decklid, L&R frt fender L&R frt door, L&R rr doors (if equipped), L&R rr quarter panel. Replacement of labels is not allowed. Replacement parts must be marked with the manufacturers trademark, the DOT and the letter R.
