Notes

Additional Equipment

Fitted luggage, two-tone paint, front bench seat (buckets are standard), reclining seats, whitewall tires, rear jump seat (coup� & convertible only), fabric or metal sunroof, Becker or Blaupunkt radio. All models available as RH drive, depending upon country of destination. Autos shipped for sale in the U.S. were required by U.S. Department of Transportation, D.O.T. to be fitted with sealed beam headlights, white or amber "beehive" or "bullet" turn signals mounted below the headlights. Fender top turn signals were required to be white, but were often replaced with amber, which was more readily available. Some cars were required to have a small red reflector mounted inboard of the tail light assembly and above the rear bumper. There appears to be great inconsistency regarding the application of U.S. D.O.T. requirements.
