Luxury and Sport Combined

Jscheu, 12/05/2020
2020 Cadillac CT4 Premium Luxury 4dr Sedan (2.0L 4cyl Turbo 8A)
My All Wheel drive Premium Luxury CT4 surprised me by how well it handles on the road, both straight way and especially curves. In a 6 inch snow this past week, I actually felt safer the way it hugged the road and handled than my 4 wheel drive truck.Safety features galore.Even though there is not much room in back for passengers, by moving the front seats up.some provided enough leg … room. The 4 cylinder is surprisingly spiffy and also gets over 30 mpg on the road.
