Colonial Buick GMC review
Our 2013 Terrain was purchased from Colonial back in 2016. It has almost 222,000 miles on it. Still performing well. We always get great service at Colonial. Kimberly is our service representative. She does a great job. This time was a fluky thing. The only key we had was lost and we had to get a new set of keys. A frustrating situation was made easier with help from Colonial and Kimberly.
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.

Excellent people. I was working with Jeff Williams, who has been great, but Thomas Maloney has been wonderful to work with in Jeff's absence as well.

Colonial Buick GMC review
Kimberly is the best. Her and her team always take care of my 2024 2500HD.
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.

John Miles Chevrolet Buick GMC review
I had an amazing car buying experience with Sam at John Miles Chevrolet! From start to finish, he was absolutely phenomenal. It had been over a decade since I last purchased a vehicle, so I was feeling a bit overwhelmed, but Sam made the entire process smooth, clear, and completely stress-free. He kept me in the loop every step of the way, especially about when the car would arrive in-state, and made sure I understood each part of the buying process. No pressure, no confusion?just honest, helpful guidance and great customer service. If you're looking for someone who?s knowledgeable, patient, and truly cares about helping you find the right vehicle, Sam is your guy. I couldn?t be happier with my experience!

Colonial Buick GMC review
Great customer service and they always do a great job ! I?ll be a forever customer! I live to come here for my oil changes!
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.

Colonial Buick GMC review
My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.

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.

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.
