Good list. Although I would definitely put the GT4 in that list over a bunch of those cars.
In fact, that omission is pretty stupid of Road and Track... The Cayman is one of the best driver's cars out there, and they didn't include the GT version of it on their list.
Yet, they included a base 911 with the new turbo engines when the GT4 is as fast, has an NA engine, more HP, and is the better driver's car overall, and costs couple grand less.
