I had a white/tan 1977 320i 4spd and a 1983 black/black 320is 5 Spd...both great cars. I was living in Portland, Oregon at the time. If I parked the car anywhere but in a locked car garage overnight, the next morning both emblems would be missing along with the Blaupunkt radio. It pissed me off so much, I ended up buying a 1984 Supra. Ah, the good 'ol days
