Meet Mario Spitzner. He's been at AMG since around the time a man by the name of Senna was racing W201s. If you know what that means, watch this interview. If you don't, you have to watch it twice. Either way, you'll be an AMG nerd before it's over.

This week on AFTER/DRIVE, Mr. Spitzner regales us with stories of AMG's history, from that fateful day at Spa when two men, from a workshop in Burgstall an der Murr, turned a massive 300SEL into a podium finisher, to all the fateful days in AMG's history that came after: The Hammer, the Senna days, the superchargers, the "63," the Black Series, the first four-cylinder AMG engine.

Hear an insider's account of the prodigious AMG motorsports and tuning legacy from someone who was there for most of it.
