Ewing Buick GMC review

The customer service, the compassion and understanding

The customer service, the compassion and understanding were truly great. Suzanne and Jason were incredibly kind, very responsive and explanatory and provided us with all around amazing service. We were contacted quickly after our online inquiry and Suzanne was happy to help us answer all the questions we had. We are out of state and the process in which the paperwork and transport of the vehicles were done was flawless. We thank you all for your expertise and kindness. We will be back when the time comes and will most certainly refer all who are in the market to your dealership.

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! ?????

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.

Mike Rose was our hero when we were looking for a almost new Tahoe. We were in Hickory and Morganton area, we were looking at a Tahoe at another Large dealer in Hickory, they SOLD it while we were looking! Called Mike Rose at Parks GMC and he took our name and number late February, 3rd He told us what he had on the lot and held it for us overnight. We arrived Feb 4th. to look at the 2025 Tahoe, High Country. We agreed on price and we drove it home. Love Mike Rose's attention to detail, southern charm, very nice, going above and beyond to help us. He was patient teaching us the new buttons and devices on the High Country Tahoe. We will purchase another new vehicle from him next week. People are important! Mike listened and treated us with respect and Southern Hospitality when we were looking for a vehicle.

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!
