Sunset Ford of Waterloo review

Honesty

I was attempting to purchase a clean looking Chevy Colorado and worked with Kyle Brewer. I am out of state so Kyle worked hard to show videos, answer questions and do an iphone facetime walkaround of the vehicle with me. I never did get a chance to make an offer. The following day when I called the dealership Kyle was away but I spoke with Julian Henson and he informed me that they could not sell the vehicle due to an improper and unsafe lift kit installation that made the vehicle unsafe to drive. Their honesty saved me time off work and flight costs. Had that been a dealership in MY area I would have had an unsafe vehicle pushed on me. I never once felt pressure to purchase and felt treated fairly and honestly throughout the process. I even received a call from the manager afterwards to follow up with me. Would be more than happy to do business with them in the future.

Had a oil change and tire rotation on my Toyota truck and the service I received was outstanding. The service department kept me informed on what was going on and asked before doing anything extra. Truck was clean inside and out when handed back to me. I would highly recommend DeeryBrothers service department and appreciate the great service I received.

2021 GMC Sierra 2500 SLT 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.

Superior Auto Sales review

Went Home with My Perfect Car! Twice!

I bought a Chevy Trail Blazer four years ago from Superior. It is still a joy to drive and very reliable. In June 2020, in the height of the Pandemic, I needed a second car and knew just where to look! Brandon Motard helped us find the Trail Blazer and helped us find a gorgeous 2013 GMC Acadia. This well maintained beauty floats down the road like she is brand new! Joe Usewicz was key to finalizing the deal, such as handling getting the registration and license plates, even though the DMV is closed. Do yourself a big favor and save yourself some headaches by seeing Superior first. No pressure and very high quality used cars, trucks, and SUVs. My third car will be from Superior!! They are honest and treat you right. Just look at the other reviews and count how many people are repeat customers. There is a reason for that! I made the two hour drive to find my perfect car and it was worth every mile to get there!

I am a new customer to the Johnson auto group, and after my experience will certainly be a returning customer. The sales staff, specifically Shelby, was amazing. They were attentive, fair, reasonable, and transparent throughout the entire process. I am so happy I decided to purchase from Johnson GMC. Ultimately, I left the dealership with a new truck and a great experience where I felt that I was a valued customer and that my business was truly appreciated.

Allen Tillery Chevrolet review

I went to the dealership to look at a couple of vehicles

I went to the dealership to look at a couple of vehicles to get a feel for which one I would go with. I was stressed and planned to just look, sell my car, and then make the purchase. Mr. Herbert Hunter presented options that allowed me to drive away in a new vehicle that same day as opposed to waiting a week or two. I recommend Allen Tillery. Allen Tillery has a large selection, professional staff, and will provide you with options to what you need or are looking for with your vehicle purchase.
