Well worth the 6 hour round trip!
It had been 36 years since I had purchased a new vehicle. The process with Marty was so smooth. From the first email to setting up a time to come in to getting my trade evaluated to finance paperwork; it all went smoothly and quickly. I can see why Marty gets so many positive reviews. Blake was great as well. He explained financing details as well as what they had to offer with warranties and protection packages with no pressure to buy. This was an awesome experience all the way around. I will enjoy my 2020 Civic Hatchback!
Good afternoon everyone, yes, I’m a lady and I’m an owner
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

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!

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

Great deals, Great people, Purchased several cars thru this dealership over the years, excellent place to purchase a car and have it serviced.
Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

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

Great!
Dealing with Dahl was a very pleasant experience. We were treated respectfully. No high pressured sales pitches. Javier Calleja was our sales consultant. He was very professional and answered all our questions and made us comfortable with the entire process. I really appreciated the IT class with Dan Medberry. It was a great help since it has been a long time since we purchased a new vehicle. A lot has changed! Both Javier and Dan are to be commended for the fine job they do.
I have loved and owned Chevy and GMC midsized trucks
I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

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.

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!

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!
