I had a lap in the Alpina 3 litre with the works driver circa 1972 at the Buchloe test track. He didn't say much but he sure made that car sing; cured me of the notion that I could become a "race car driver".
Lauda, finishing the last few hours of his contract with Alpina and not happy about giving rides to snot nosed customer's kids.
Drove the 69 2002 fully rally prepped car back to London for my father. Epic.
