Well, my wife cant get over the fact that town eastford has had her car for 3 months and they just dont let us know updates,should I request them to buy it back and buy a different vehicle,let the public decide
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Great Experience
My husband and I were in the market for a newer yet used car. We found the car we were looking for on their website and started the process online. Once we got to the dealership, they already had the car pulled up and ready for us to see. We decided we wanted the car and finance worked quickly and efficiently. We had a wonderful buying experience...and AFTER the fact, we noticed a leak by the brakes. They called us in immediately because of that being a safety hazard, put us in a loaner car and have been taking care of us! VERY pleasant buying experience!
