Leno would be good. I think Dennis Leary might not be bad in the place of Tanner but you really do need someone who really knows cars.
I never really had any appreciation for European cars but I've fallen in love with the Aston Martin since watching Top Gear.

With a car like that, you'd always smell of Connolly leather. An unfair "pheromonal" advantage. ;-)
BTW, if you like motorsports stuff, check out Eric Bana's movie, "Love the Beast". Interesting celebrity autobio/car freak story.
