The customer service at Luther Brookdale Chevrolet is premium service. The workers are very professional and nice, I'm overly satisfied and pleased with my experience with the Luther Brookdale Chevrolet team. Thanks
2018 GMC Sierra 3500 review
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.

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!!

Cobb Luxury Cars review
May 20, 2026 Thank you to Levaugn at Cobb Luxury Cars. We found a car that is beautiful and should give years of dependable service. The communication was excellent and the purchase process was painless. The price was excellent, as well. 5 stars.
2018 GMC Sierra 3500 review
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.

Doug Smith KiaReviews
Doug Smith Kia review
Go here for your next car! They had the perfect vehicle at the right price, with outstanding sales and customer service. Javier is an excellent sales person; knowledgeable, personable, and he followed up with me after the sale as well. He and the sales manager went the extra mile to put the deal together for me and then make sure I had everything I needed and wanted. It was so easy to buy my car with them. 100% would recommend to everyone. The car had been fully repaired, serviced, and inspected before they put it out for sale, and they happily provided all records to me. After slogging through dozens of shady dealerships and terrible cars, I found Doug Smith KIA was impressive, professional, and so refreshing to work with.

Good experience and great price!!! Greg helped us with our purchase and was great to work with both online and in person. Highly recommend them if you are in the market for a used truck or SUV!
2018 GMC Sierra 3500 review
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.

We bought a car from them on 8/20/25 and it was a great experience. Jossue and Tim were Great people to work with. Definitely would do it again.
2018 GMC Sierra 3500 review
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.
