How is the North American-spec M roadster cosmetically different from the European version?
The North American-spec version of the M roadster is cosmetically very similar to the European version, but can be identified by its amber side marker lights (and turn signal lenses on cars built before September, 1998) in the front bumper, “free form” headlights in place of the ellipsoid units and twin side-mounted rear license plate illumination lights instead of the single bumper-mounted design.
