For proof, we suggest you check out the two videos after the break to see vintage prototypes like the Ford GT40, various Lolas and a smattering of McLarens take to the track. Then, to top it all off, we have the '60s sports car class, which includes such iconic masterpieces as the Shelby Cobra (in both hardtop and Daytona Coupe guises), Ferrari models that include the famous GTO and the so-called Breadvan (a short-wheelbase 250 GT), plus a slew of machinery from Maserati and Aston Martin.
Did we mention these priceless classics are racing well-to-wheel in the pouring rain? Enough already, click past the break to watch the slip-sliding action for yourself.
UPDATE: Sadly, the embedded videos are not playing, but we still hope you click on over to Axis of Oversteer to take in the historic racing action.
