As a woman who honestly knows nothing about cars, I was
As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!
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.

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.

I met with Dave Fisher, he made me feel very comfortable
I met with Dave Fisher, he made me feel very comfortable from the beginning all the way through the whole process of buying a used vehicle. No pressure, no stress. I was very happy I decided to go to Sapaugh GM Country. Thanks Dave for making the process and easy one
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.

I have owned a Dodge Cummins and this 2006 GMC
2006 Duramax is great truck for pulling my travel trailer. When just the truck over 20 mpg and 13 pulling a 8,000 trailer. Very comfortable and stable on the road, plenty of power. I installed a Pioneer system with 7" screen, blue tooth, dvd, satellite radio and android auto. With that I have every option of a new truck except the collision avoidance and lane change type items. Great performance!
