How is a North American-spec E28 M5 cosmetically different from a Euro-spec E28 M5?
The North American-spec E28 M5 uses the same government-mandated sealed-beam headlights (all four of the same diameter) and 5-mph bumpers with integrated side marker lights as all U.S. and Canadian versions of the E28 5 Series. However, the M5 adds a special front airdam designed specifically for the North American front bumper as well as the M-Technic rear spoiler fitted as an option to some European-spec examples. Though these items are not unique to this model (both are also found on the E28 535is), the M5 can further be identified by its Shadowline trim, “M5” grille and trunk-lid badges plus the 16-inch cross-spoke alloy wheels.
