TCC’s Bottom Line
The 2020 Acura RLX’s familiar shape hides a forward-thinking powertrain. In its final year, the 2020 Cadillac CT6 is a tempting look at what could have been from the luxury brand. The 2020 Kia K900 piles luxurious fittings and features into a stylish sedan body, and tops it with an excellent warranty.
