Our experience was nothing less than awesome.
Our experience was nothing less than awesome. Alex our salesman went above and beyond anyone we have ever dealt with. He made it pleasurable and seem less!!
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

My overall experience at Dave Sinclair Lincoln has been amazing. My sales rep Dee-Davis. She did such an amazing job with the whole process. Great communication. Dee got me approved in minutes and I was out the dealership just as quick. I truly recommend purchasing a vehicle from this dealership and also Dee-Davis.
2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

Went to look at a Rav 4.
Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.
This truck has a jerk when changing gears sometimes.

Sales consultant; Bob Reasoner, helped me with the car I was looking for. This dealership has a no rush, clarity policy that aloows you to inspect the car to your satifaction and present you with a car that has been safety inspected & detailed. Qualification and rates were resonable.

Reliable and comfortable.
I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

A REPUTABLE CAR SALESMAN!
Ed Rapien has been our salesman for 15 years for Ford-Mercury products. He is very professional, sells the cars for a fair price, helps with backing up any problems we have had, & I actually feel he is an honest car salesman.My only complaints are that Ford is no longer making sedans or the Mercury brand. These are not Ed's fault, however. Thank heaven they kept him when dealership was sold from Price-Gnade to Trenary.

On July 15, 2023 I purchased a new car from Dean Team Volkswagen in Kirkwood. Eddie was great to work with and made buying a new car painless. We were in and out in no time. Thank you Dean Team...awesome customer service, we will be back!
I've had the truck a month, and so far so good!
It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

Excellent Service!!
I was in an accident and my car was totaled. I wanted to replace it with a new Nissan Rogue, it the car dealership that I got my last one at was no very anxious to help me find one since I hadn’t received the check from th insurance co. yet. Todd Eversgerd went out of his way to find a car, get the extras that we wanted installed on it, kept in contact with me re: when the car was delivered and the work was done, etc. He even went so far as to try to match the color of paint on the number of our license plate that had been scraped off during the accident! Eva’s very professional and went above and beyond in all aspects. When we got there, he was busy with someone else across the street at the VW dealership, so he had Matt help us wile he was over there. Matt also was excellent. He went over everything that Todd had written down including giving us the manuals, having us watch the videos, introducing us to the finance manager. Afterward,Matt took us out to the car went over everything about the car,and programmed our phones into the car. He then called Todd so Todd could make sure we didn’t have any other questions. I have never had anyone go to the lengths that stood went to make car buying so easy.Will definitely be back for our next car!
Would buy again!
Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family
