which brand of exhaust system is that?
Nice coupe! Looks pretty good! The Motag is only 3 numbers off mine. (7224) Maybe ours were on the shape shipment to Switzerland! Mine also has a manual sunroof and manual front windows. If you email the BMW classic group (email@example.com) with the vin you can figure out the original color and build date.
