The Car Connection's Take

TCC Rating

8.0
8.4

TCC’s Bottom Line

The 2017 Cadillac CT6 has a spare, light appeal that runs counter to its German rivals; with a starting price in the $50,000s, it's a great value, too. The Mercedes-Benz S-Class lineup is more diverse than it's ever been and is still the benchmark by which all full-size luxury cars should be measured.
