Had a great experience purchasing my new Yukon. James was super helpful and knowledgeable and the whole process was easy and pleasant .
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Ross Downing GMC Cadillac review
Overall a good experience! I wasn't being pushed by the salesman at all, which is how it should be. Also, answered all of my questions honestly. We will buy from them again when we need another vehicle. Caleb (salesman) did awesome, never felt awkward, or uncomfortable. Scot
2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

Ross Downing GMC Cadillac review
The oil change and tire rotation service went well. I have always taken my vehicle to get the oil changed since I made the purchased from Ross Downing. Great service and very professional.
2026 GMC Sierra 1500 review
This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.

Ross Downing GMC Cadillac review
Our salesman, Landon Crane, is new and even didn’t have his business cards yet but he’s gonna go far. He was extremely polite, willing to answer questions and had no problem getting up to ask about an answer he wasn’t certain of. I appreciated he wasn’t pushy, condescending, or fake. He may be young and just getting started but you won’t go wrong by requesting him for your salesman. The young man knows how to give an appropriate handshake on top of all his other positive qualities. From start to finish it was a relaxed buying experience. Give him a call!

This is a great truck. it drives and handles so well. I feel very safe driving this truck. The suspension is the best of any truck I have ever owned.

Laura Buick GMC review
We had a great experience from start to finish. The team took the time to listen to what we were looking for and helped us find a vehicle that checked all of our boxes. There was never any pressure to buy?just honest guidance, patience, and helpful answers to our questions. We truly appreciated the relaxed, customer-focused approach and would highly recommend them to anyone looking for a positive car-buying experience.

Laura Buick GMC review
As always the experience at Laura Buick GMC was excellent and we could not be happier with the vehicle we purchased. The entire team starting with our sales person went above and beyond to make sure we ended up with the vehicle we wanted at the best price possible. We have bought multiple vehicles from Laura Buick GMC and will continue to buy from them in the future.
