As a woman who honestly knows nothing about cars, I was
As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!
great vehicle
traded in my 2013 buick enclave for this 2023 gmc acadia. i think the ride is a little better , fuel mileage is better over all comfort is great. Ed at Patriot Buick GMC was great in explaining all its features.

Diesel AT4 it!
GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

Justin Scheaffer supported my acquisition of a 2025 GMC
Justin Scheaffer supported my acquisition of a 2025 GMC Denali truck with total customer care in mind. From finding the exact vehicle I wanted to it delivery, Justin was there, front and center - An Outstanding job; definitely a go-to professional who gets my highest rating!! Thanks Justin - Will stay in touch!
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.

My husband and I recently bought a Dodge Ram from Colton
My husband and I recently bought a Dodge Ram from Colton and we had the most pleasant experience! He got us in the truck that met all of our needs within the first 10 minutes. He answered all of our questions, explained the paperwork thoroughly, and made the overall process of buying a car completely painless. We are definitely repeat Federico customers!
My Work horse.
I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Bought the car I had researched from Suntrup KIA.
Bought the car I had researched from Suntrup KIA. The salesman Moe was way more than helpful.every one I dealt with was super helpful friendly and seemed very genuine. Moe spent as much time as I wanted showing me features. And even would explain more about her telluride that she bought somewhere else. I have bought many cars in my life. But I can honestly this was my best car buying experience. They all did try to meet my terms and I left feeling I got a great deal. And I did.
We love our GMC Terrain !

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
I saw this car driving by the dealership and
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!

Pretty easy process for us.
Pretty easy process for us. We knew what we were already going to be looking at because we really wanted a hybrid. We bought it used but the dealership did a really good job inspecting it and making sure it not a lot was wrong with it. If it weren't for the smoker who was in it last I think the headliner would be cleaner but otherwise the car was in good shape inside. There were a few dings here and there on the outside. The car drives and runs really smooth and overall was happy.
Love love LOVE
I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.
