Big thank you to the service department at Mark Wahlberg
Big thank you to the service department at Mark Wahlberg Chevrolet! I was in Columbus traveling 500 miles from home when the tire pressure light on my 2018 Silverado came on with a zero pressure indicator. The guys in service were empathetic to my situation and immediately started inspecting the tires and checking the sensors. Turns out the tires were fine. One of the sensors had gone bad. I had peace of mind to drive home eastern PA. I asked what I owed and was told no charge, glad they could help. Thanks again.
I have a ct6 platinum with super cruise.
I have a ct6 platinum with super cruise. 4 years now bought used . I have driven it 60k miles. Not a single problem. Normally gets 30mpg with the 3.6v6 on highway about 24 in town. The car handles fantastic on any surface. I love it. Highly recommend it.

I decided to bump my search up a couple months after
I decided to bump my search up a couple months after speaking with Chase Tomasi. Chase took the time to show me a truck he had mentioned earlier in the week. Chase is very professional and you hear how companies want you to feel like a friend, he walks the walk. We spent more time talking about everything but the truck, vacations, family, and whatever else came up. The truck sold itself but Chase made sure I saw it. He could have tried to sell me a more expensive truck but he knew I liked the one I bought. Tony made the financing easy and quick. Don't hesitate to visit Coughlin Marysville and when you do, ask for Chase.
Amazing...and American!
Recently bought a used CT6 w/2.0 Turbo (2018 with 39K miles). Have put only about 500 miles on it so far, but, WOW!!! This car is amazing! This car lives up to it's reputation as a builder of premium American luxury vehicles. My las t Cadillac was a 2000 STS...which was mediocre by comparison. It is soooo beautiful inside. I like that the screen is integrated into the dashboard. It's size takes a bit of getting used to, as my last car was a Mercedes E250. I test drove the 2.0 turbo and the 3.0, and found the 2.0 Turbo to be equally responsive but smoother. Exterior styling is simple clean and exudes luxury. I get so many compliments, heads turns and such. I love the Apple Car Play feature that projects what's on my phone to the in-dash screen. Recently did a road trip and got an AVERAGE of 33.4 MPG on the highway. I am getting 25 MPG+ around town. To me, that's pretty impressive for a car his size. In keeping with Cadillac's reputation, this car drives so smooth and quiet. Last time I drove a car this quiet and smooth as a Lexus LS460. At $30K less than the price of an average EV, it will take a lot of gas to make up the cost difference of those overpriced cars.
