I really liked everyone there that we met. When I drove the Jeep home Steve even was talking about maybe trading the truck in later. Mike was really a great salesman, I would give him 6 stars.

Mohawk Chevrolet review

I've purchased probably 20 new vehicles in my life thus far. This was the best purchase experience I've had to date. Dan, Kasey and the service team were exceptionally patient...I had a lot of questions. The service team was also exceptionally helpful as well answering some very detailed and specific questions with respect to the vehicle I was purchasing. I have always liked GM vehicles but having a great dealer to stand behind the product is more important than anything to me. The facility is state of the art and I like that but the people seem genuinely interested in doing right by me. If they continue to treat me as they have I will have little reason to ever look anywhere else for a vehicle. Really a great purchase experience and a really good deal as well.

2021 GMC Sierra 2500 AT4 review

Early to tell truck has less than 100 miles

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Sheehan Buick GMC review

Response to my inquiry was prompt and courteous.

Response to my inquiry was prompt and courteous. So was the follow-up as the sales agent checked with me regularly. The initial internet presentation of the car wasn't great as pictures were of "other" cars of the wrong color, etc. I didn't buy the car so I don't know what happened after a few days.

Garber Chevrolet Midland review

I had a great experience coming in for an oil change.

I had a great experience coming in for an oil change. The drop-off process was quick and convenient, and they even offered me a ride to work, which I appreciated, although my job is close enough that I chose to walk. My appointment was at 9:00 AM, but I dropped my car off at 8:00 AM before heading to work, and by 10:15 AM they had already called to let me know it was finished. The service was fast, efficient, and everyone was very friendly. I have always been treated wonderfully anytime I?ve had my vehicle serviced here. Highly recommend! ?????

We had a great car buying experience with Friesen Ford.

We had a great car buying experience with Friesen Ford. Louie and his team were extremely professional and wonderful to work with. We purchased a used Expedition that had some unexpected problems come up several days after the purchase. I notified Louie and his team corrected the issues right away (free of charge). We love our Expedition and will definitely recommend Friesen Ford to others!

Chevrolet of Bend review

I had such a great experience at Chevrolet of Bend!

I had such a great experience at Chevrolet of Bend! From start to finish, everything was smooth and easy. Jonathan Stewart was incredibly personable and made the entire process stress free. He really listened to what I was looking for and never made me feel rushed or pressured. The finance director, Scott Keller, was just as great - friendly, efficient, and transparent about all the details. I appreciated how quick and straightforward the paperwork process was. Overall, it was the easiest and most positive car buying experience I've ever had. Highly recommend this team!
