The Daytona Coupe was bested by the GT40.

But if you're looking for something you can whip around the track and are not locked into vintage racing, then you should look at a Corvette. The Z06 is the best track monster for the price on the planet and you can pick up a low miles car from someone that has only used it on the street and switch it to track use for about 50c on the dollar. They build tons of them and so are not considered an investment. Bob Bondurant's school in Phoenix used Corvettes before they switched to the Dodge offerings. I was skeptical at first haven driven older Corvettes and didn't consider them a real track-worthy car, but the Z06 (and the lesser version with the same car except for the non-dry-sump engine)) genuinely surprised me.

Also, Ariel Atom.

As a dedicated racer, Radical makes a really hot car.
