The Car Connection's Take
TCC Rating
6.8
7.2
TCC’s Bottom Line
The 2017 BMW 6-Series is a luxurious jack of all trades (speed, style, comfort, and quality) but a master of one: grand touring. The 2017 Mercedes-Benz CLS-Class is the first of its kind and in need of a makeover. It's still timeless, but it's also time for what's next.
