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.

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!!

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.

Cobb Luxury Cars review
I really enjoyed working with Ms Car Lady,. She's far from the average salesperson. Got me a good warranty and great payment'. I highly recommend Ms Car Lady if you're Car shopping
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.

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
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.

Sakelaris Ford of RollaReviews
Sakelaris Ford of Rolla review
My wife and I wandered into Sakelaris Ford looking for a unicorn: an F-150 XL Regular Cab Short Bed 4x4 with the 5.0L V8. Ben Tinker took that challenge head-on, searching the internet for hours. Once we realized just how rare this truck was—after contacting every Ford dealer within 300 miles only to learn that either the vehicle was already sold or the dealership had “upgraded” it (for an additional $20–30K)—we thought about giving up. But not Ben. He had a mission. He widened his search to the entire country. Over the next few days, Ben reached out to practically every Ford dealer between here and both coasts. He stayed in constant contact with us, telling us not to lose hope and to keep our eyes on the prize. Then he found it—the 🦄. A nearly untouched F-150 XL RCSB that matched our exact specs. With the ease that comes from years of experience, Ben and his sales manager worked the phones, convincing the other dealership to let go of their prized truck and ship it to us. Now the fun part: negotiations. The sales manager drove a fair bargain and worked with us on price. Even after taking a small hit on the delivery cost, we felt completely comfortable pulling the trigger. We were approved over the phone and signed all the paperwork effortlessly through DocuSign. Truck is home, we’re thrilled, and we couldn’t have done it without Ben and the team at Sakelaris Ford. Highly recommend!
