TCC’s Bottom Line
The 2018 Chevrolet Corvette delivers unmatched performance for the dollar and the features to go with it; the looks are arresting but perhaps too aggressive for some tastes. The 2018 Mercedes-AMG GT performs brilliantly on any kind of pavement, making it one of our favorite modern sports cars. The 2018 Porsche 911 is a superlative sports car that has defied its age. It’s a classic, but performs better than nearly any newcomer to its arena.
