Vintage cars at Elkhart Lake - a visceral experience

At the vintage racing weekend there are two concours d'elegans - beauty competitions for cars. On Friday night are the race cars, and on Saturday night, the street cars. The following pics are from the race car night, and a beautiful night it was. Lean and voluptuous racing beasts filled the streets, and the cars weren't too bad, either.

Ah, velocity stacks! My favorite!
Racing MGA! Cool!
A Crossle. Some crazy British thing, I think. Ross would know.
Sinister racing corvette.
Racing Jaguar! With rivets!
Another of the odd-ball makes that show up in vintage racing; a Porsche-powered Elva. Or is it an Elva-bodied Porsche?
This is a helicopter turbine engine. In a race car! It sounds fantastically bizarre!
The picture says it all.
Clancy's Sprite, with a McLaren in the background. The extremes of vintage racing.
