Saw the Sauber Formula 1 stuff at the BMW Welt in Munich. Lots of great stuff in the museum but I was most intrigued by the Formula 1 (albeit limited experience in BMW) and certainly motorsport. Learn quite a bit about some cross pollenation even during the brieft stink of modern F1 in BMW. Wish they would jump back in and win some awesome races. The hall had a fair amount of stats on BMW in endurance races, including BMW engines that powered championship cars.
