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!
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Conan Thomas was my service advisor and the service was excellent. Took care of everything and made this service call as easy for me as possible. I will always go back to Sapaugh.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

This is the 3rd vehicle I have purchased and currently leasing a new vehicle from Sapaugh. Rich Konold is the best sales consultant. He knows the vehicles and can help you match your wants/needs to the best vehicle for you, and get you the lowest price.
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.

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

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

I have owned a Dodge Cummins and this 2006 GMC
2006 Duramax is great truck for pulling my travel trailer. When just the truck over 20 mpg and 13 pulling a 8,000 trailer. Very comfortable and stable on the road, plenty of power. I installed a Pioneer system with 7" screen, blue tooth, dvd, satellite radio and android auto. With that I have every option of a new truck except the collision avoidance and lane change type items. Great performance!

I have owned my Acadia just under one year.
I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

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.
Perfect for us!
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

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!
