Taking a 12-year-old CTS Sport Wagon to a Cadilllac

Reviewed by JHB from Alton, ILFebruary 28, 2025

Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.

Paid $9600 for a truck and didn’t even get it off lot and engine light was on. Service stated that it was all good to go and fixed. Get into truck tonight, mind you we only had it 2 days and haven’t driven it again until tonight, engine light came back on. Ran codes and they didn’t fix the problem. We went there because we thought we were getting a great deal and a more reliable farm truck. You would think since they had the truck on their lot to sell. Well we will NEVER DO BUSINESS WITH THEM AGAIN!!!!

I highly recommend this business. I was completely impressed with Angelo, and the service department. Very knowledgable, reliable and honest. Angelo took the time to answer all of my questions, and provided me with available options from repair to replacement.
