2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Highly Recommended to buy On-Line
I bought a 2020 Chrysler Pacifica Hybrid through Driveway.com from Volkswagen of Salem. This was my first time buying a car on line. I was nervous about sending a cashier's check before I actually saw the van. Lian from Driveway.com handled most of the final paperwork, sent extra pictures of the van, worked with me to see the van before I sent the cashier's check. Once I saw the van I sent the Cashier's check as promised. The Lithia dealership near me let me drive it home the next day. Kristina from Volkswagen of Salem helped me with the registration of the van in California. She took the time to explain the registration process, extended the temporary plate and registration, sent the necessary docs to the DMV in CA, emailed me copies of the docs, DMV in CA received it, all the docs were in order, and I received my new license plates and Calf. registration that day. The entire Lithia team made the transaction seamless and kept me up to date on the process of purchasing the car out of state. Buying on line widened my selection of this van and provided a reasonable price. Highly recommended.
Best truck I've owned yet
What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

Cary was super helpful with my car purchase.
Cary was super helpful with my car purchase. Appreciate his experience and expertise. Thank you!
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

So far have loved my 2020 2500 HD 4x4 diesel
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

Best Dealership Around!
We would like to thank Dee Motors for your service. John and Ron took care of all our questions and concerns when we showed interest in purchasing a new Mojave Gladiator. We must say that this was the best car shopping experience ever. John was extremely attentive and we appreciate the additional incentives, Jeep hats and floor mats that were provided in our purchase. Your dealership delivers incredible customer service and professionalism. We will definitely be back for future purchases and will encourage our family and friends to do the same.
