TCC’s Bottom Line
It’s back and the 2020 BMW 8-Series is available in any style except SUV. You go, BMW. Powerful, track-ready, and comfortable, the 2020 Mercedes-AMG GT 4-Door Coupe can do it all. The 2020 Porsche 911 improves upon the sports car icon’s incredible performance while adding needed safety and connectivity features.
