TCC’s Bottom Line
The 2021 BMW 8-Series is a gorgeous statement piece that strikes an enviable balance between performance and usability. The 2021 Mercedes-Benz AMG GT 4-Door Coupe is a worthy rival for the best performance sedans on the market. The 2022 Porsche 911 brims with technology and luxury, and bristles with pavement-conquering confidence.
