How is the exterior of the E39 M5 distinguished from that of the regular 5 Series?
The E39 M5 is equipped with several unique exterior cosmetic items that distinguish it from other 5 Series models. The front fascia features an enlarged grille with wider chrome trim around the “kidneys” as well as a unique M-Technic airdam with mesh over the central intake. The rear of the E39 M5 can be distingished by a small body-color lip spoiler (deletable upon request) as well as a unique rear bumper and lower diffuser that incorporates two pairs of dual exhaust outlets. There are also M-designed rear-view mirrors (which fold up electrically), the unique 18-inch M Parallel Spoke II alloy wheels and three “M5” badges that adorn the exterior of the car, one on each of the side mouldings and a third on the trunk lid. Most E39 M5s were equipped with high-gloss Shadowline (black) window trim though the chrome trim from the standard E39 could be specified as a no-cost alternative in most markets. All E39 M5s have clear turn signal lenses.
