Martin Bürki from Mattmüller Motorsport recently sold his BMW E30 race car. The car was powered by a naturally aspirated 3.0 L S50B30 inline-six making 370 hp and is paired with a Quaife six-speed sequential transmission. To commemorate the change in ownership Hillclimb Monsters put together a compilation video of Martin and the E30 competing at Ayent-Anzere, Gurnigel, Oberhallau, and St. Ursanne-Les Rangiers hill climbs in Switzerland.
