The CT 6 is a solid car, reliable but damn expensive to own and operate. If you got the scratch, this car will satisfy the itch, but like i said, this car scratch is intense. The CT6 got that old time flair with enough modern to satisfy without looking like a glorified jukebox like how the cars look today. If I wanted a car that was a lightshow I would have gone to Vegas. If you want solid that looks and feels like, and most importantly drives like a luxury driving machine, this car will more than satisfy you.

GM (not just Cadillac) has a problem with its 8 speed transmissions up through 2018. Sometimes a flush with Mobil 1 (blue label) can take care of it. If not, then a replacement torque converter fixes the “shudder” problems. A spendy fix unless your powertrain warranty is still in effect. With its new torque converter our 2018 now runs like new again; with crisp handling, good response from the 3.6 liter engine and a very comfortable ride.

This is my 5th Caddy and it doesn't disappoint. The transmission is the vehicle's only flaw. Hard shifts ruin an otherwise perfect experience. Working with a dealer to repair this concern but based on the other reviews, I have little confidence.

Get it in writing the price you're willing to purchase, because if it's too, good to true, then it probabily is.
