If I had a few years, an unlimited supply of cash and every major car-company rep on speed dial, I'd visit every company's factory race shop, museum and legend house. Call it a fat bucket-list entry if you want. Recently, JF Musial got to go to Audi's.

This week on /INSIDE QUATTRO, we get a tour of the Audi historics shop with company historian Thomas Erdmann. There's plenty of vintage eye candy to look at, from the short wheelbase Sport Quattro to the B5 RS4 to the 1930s Auto Unions and DKWs that started it all.

Of course, it's only the latest installment in an Audi nerd's dream travelogue.
