The Car Connection's Take

TCC Rating

TCC’s Bottom Line
The 2019 Audi TT isn’t the most exciting sports car, but with impressive tech, performance models, and all-wheel-drive, it’s very well-rounded. The 2019 Mercedes-Benz SLC-Class splits its mission between top-down cruiser and top-up thrill seeker. The 2019 Porsche 718 may never be the champion of the automaker’s lineup, but it’s a champ everywhere else.
