Great experience with this dealership. I will come back again as well as refer my friends and family to this dealership. Sales guy Dan was a big help!
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.

Best dealership experience ever
Josh was so accommodating..I have mobility issues and getting in and out of a car is extremely important to me. He impressed me so much; very honest and didn't try to sway me to buy something else since I was very firm on what I didn't want..truly appreciate his honesty. Although I didn't find a car that day, I hit the website to check what they've got and will contact Josh if I see something that interests me.
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.

Deffently tell friends and family this is the dealership to go too !!!
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 experience ever
I had the best experience from start to finish purchasing my Ford Flex. They were able to work with me in Hibbing 2 hours away to get me the vehicle I wanted. The entire staff was friendly and knowledgeable. They gave me a beautiful send-off with my new-to- me vehicle. I would definitely shop here for my next vehicle.

Jason Payne definitely made the purchase process the easiest! My husband recently had back surgery, so we were able to do everything very quickly, all we had to do was sign papers when we got to the dealership!! We were at the dealership less than an hour! We will definitely be doing business with Jason Payne in the future! I LOVE my GMC Terrain!!!

I was greeted by a pleasant worker who told me where to drive to enter your service area. Next, another worker asked for my keys and told me where their lounge, restrooms, and coffee was located. She said she would get me when my car was finished. She was very professional explaining the consent form I needed to sign. I thought everyone really cared for their customers. The building was so clean, I was impressed with everything I saw.

Buying a vehicle at the AutoSavvy in Woods Cross was a calm and stress free experience. I had the chance to work with Jarel and he was attentive, not pushy, and a great listener to what I was looking for! He answered all my questions , and ensured that I drove off feeling confident and satisfied with my purchase! The entire team's dedication to excellent service really stood out, and I drove away from Woods Cross knowing I made a great choice with a great new truck! I highly recommend this location and if he’s available, ask for Jarel! Thanks AutoSavvy in Woods Cross!
