Custom BMW E9 Coupe with M5 Engine Listed on Bring a Trailer Germany

A custom BMW E9 Coupe with a 400-horsepower V8 engine and six-speed manual transmission is currently listed on Bring a Trailer Germany. The car was created about a decade ago by German enthusiast Michael Oberhauser, who merged an E39 M5 with parts from two E9 CS coupes. The transformation involved removing the M5's upper structure, shortening the floorpan by roughly 8 inches, and welding an E9 roof into place.

9-liter S62 V8 engine producing 426 horsepower. The interior includes a modified M5 dashboard, heated Recaro seats, and dual-zone climate control. The car is equipped with KW adjustable coilovers and M5 brakes. According to a build story from Motor Trend, much of the metalwork was done in Romania by skilled craftsmen who shaped custom panels by hand.
