They had a grunch of 'em, going all the way back to an MG TC. Somehow they did not have a Corvette. All American, cheap for what it did, very fast, good car. I remember going up to Watkin's Glen NY many years ago to watch the Can-Am. The Glen also ran off a "production"sports car race that weekend. That year the only two production sports cars that competed were Porsche 911 and Corvette. Nothing else in production that year was fast enough. The 911 cornered better than the 'Vettes and would work past them in the corners. After a couple of laps of hard driving a 911 driver might think he had it made. Then came the back straight, nearly two miles long. And we could hear the big Chevy 396 V-8's come on full song. And the 'Vettes just out dragged the 911's, catching all the cars that had slipped by them in the Esses. "There is no substitute for cubic inches".
After that long ago happy weekend I always considered Corvette one of the best sports cars in the world.
