TCC’s Bottom Line

In its final year, the 2020 Cadillac CT6 is a tempting look at what could have been from the luxury brand.

The 2020 Mercedes-Benz S-Class is the benchmark for large luxury sedans.

TCC Likes

Spacious rear seat
Big V-8 for its final year
Smooth ride

Smooth, powerful engines
First-class cabin
Attention to detail

TCC Dislikes

It’s gone soon
The V-8 is hilariously expensive
Never caught on

Ready to be upgraded
Maybach doesn’t feel as special
Absurdly expensive at the top
