Safest Vehicle I've Owned
I bought a 2016 Yukon XL and after just a few weeks, a vehicle ran a stop sign and totaled the vehicle. However, the vehicle was so sturdy that even though it was a huge crash, I was not injured more than bruises. I replaced it with a 2018 Yukon XL because I know it is reliable and safe.

Branson Banks - superb salesman!
My salesman Branson Banks was supurb! He worked very hard to find the perfect vehicle for me! I definitely recommend Green Buick GMC for the purchase of your next vehicle - tell 'em Bert sent ya!!!

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

We purchased a 2023 GMC Acadia with the assistance of John Thomas, Sales & Leasing /JT and Max in Finance. To start, John made the process painless and easy. He answered every question we had. He was very patient and kind. We had a wonderful experience. Max with Finance was very nice. He also answered all of our questions as well as being patient and kind. Both of these gentlemen provided excellent customer service. You could tell they both enjoyed their job. Thank you so much!
2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

My purchase of the certified 2018 Toyota Sienna was easy
My purchase of the certified 2018 Toyota Sienna was easy and smooth at Smart Toyota with salesman Matt Seifert! This vehicle is exactly what I needed for my disabled son.
Stylish and comfortable.
Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

I started online and was pleasantly surprised by the responsiveness of their folks to text inquiries. They provided a few links to check out and generally showed my whatever I wanted. I started off wanting a used car but decided on new and they were flexible with proving me access to whichever years and trim levels they had available so I could make a decision on my own time. Very little pressure from my sales guy, Nick Scott. Very pleasant experience there and even going back to the dreaded finance guy was not a big deal. They were flexible around the times I could come in with my spouse to finish the deal and modified things in real time. Very accommodating. Good experience overall. I would recommend.

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Found my Honda Accord 1,200 miles away!
Had an amazing experience working with QC Autoplex. I was an out-of-state buyer with many questions and concerns about the process of buying a car out-of-state. Scott was very responsive, very transparent about the process and vehicle, and very easy to work with. I believe the price of the car was fair and they went above and beyond to get it ready to be sold and to transport it for me. Even after I had received the car, Scott followed up with me to make sure I was happy. Definite five star experience. Thank you!
Love my GMC HD
I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Fair deal at Eriksen
After Mcgrath tried to rake me over the coals and try to charge me $5000 over MSRP. I went to Eriksen and got an honest deal at MSRP!
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.

I have purchased all my vehicles from here and they are phenomenal!! Great customer service, attentive but not overbearing, very knowledgeable about the vehicles they have on the lot and what features they have. Staff that we interacted with were patient and understanding and great with my kids who have special needs, That really means the world to my family! When getting service done on my previous vehicle it was fast and convenient, even when we were waiting for parts they kept us updated with where they were in the process. They really go above and beyond to make sure we are happy and just make us feel welcomed when we stop in. Very happy with my new Electric Blazer!
Its a decent car, but on a car frame.
