First time buying a car online.
First time buying a car online. Jeff Rick was great. He made the process easy and answered all my questions about the car. He sent me a video of the car as well. The purchase was quick and easy for being out of state. Just waiting for the car to be transported here which was also easy to set up. Thank you.
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

It was a pleasure working with Jimmy Wolfe.
It was a pleasure working with Jimmy Wolfe.He was the last person to find a solution to my problem.My 2018 Chevrolet Traverse had a transmission issue: it wouldn't start.I went to several dealerships to buy one, but because of my credit score, I didn't get the attention I deserved. Jimmy was able to find me a car that allowed me to continue working.Thanks to him,I can keep doing what I need to do instead of staying home unemployed.Thank you, Jimmy! Keep up the good work!
I have had to of these before and I drive the xxxx
Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

Everything ok but my gps audio is not working.
Everything ok but my gps audio is not working. The car is in great shape but there are a get marks on the windows that show it wasn't tinted properly.
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

I brought ny Cherokee Jeep in for an oil change.
I brought ny Cherokee Jeep in for an oil change. Derek is very knowledgeable and extremely professional and explained that in 60x miles the jeep will get a thorough check up. Even the oil change had many things checked. They are the dealership I want all.my service to go to. I trust them to tell me what's really going on. Thank you Derek and Rairdon Dodge and Jeep. Lou Azie
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

The staff at Sterling Chevy have been so courteous kind and professional. I locked my keys in my car and they were able to get me a new one cut and ready that same morning saving me so much money and time. I had purchased my car from them originally and will continue to be a loyal customer. Huge shoutout to Arielle and Mike for all your help!!
Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

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 purchased a 2005 Corvette over the phone. The car is in excellent shape low mileage and the experience of buying this vehicle was hassle free. Also had the car shipped to Las Vegas Nevada no problems. Would purchase another car from unique Auto again.

Great experience with Berkenkotter Rastle Rock.
We had an excellent experience working with Dan & Wade on the purchase of our new vehicle. The sales team helped us through the process and were incredibly patient. Used vehicle prices are out of control and it's comforting to know there are car dealers that go the extra mile. I would rate our buying experience 10/10. We will be back when looking for another vehicle. Give them an opportunity to earn your business!
