Out in Ingolstadt, Germany, you can find Audi headquarters. Where there's a nice museum, with a great collection of vintage Audi metal, prototypes, racecars, and more. But we didn't go to that museum. Nah, because with Scotto in tow - you KNOW Audi is going to hook it up. So they take us to a storage facility deep inside the factory walls, that houses THREE floors of the most drool-worthy car collection we've seen in a long time. Maybe ever. And that's saying something, coming from a single manufacturer.
