There I was, having fun, fun auf die autobahn, when nature called. Somewhere southeast of Stuttgart, I took the wrong exit and found myself outside the gates of Audi's Neckarsulm factory. A large sign proclaimed the brutally Bauhaus industrial complex ground zero for the German automaker's R8 supercar. I was immediately convinced I was destined to park one in my garage. Of course, by then I'd been chasing R8 ownership for over three years. So, do good things come to those who wait?
