Great service by Malvin & team
Malvin and Brandon and all we interacted with were extremely nice. Malvin, our sales agent was helpful with information about the car and getting us through the process. Brandon was able to help with financing. Our 6-month-old was with us the entire time, which took about 4.5 hours, so if I have any negative feedback, it is that the process took a VERY long time. We were extremely happy with our service, and give your boy Malvin a raise!

Diane was a great sales person. She went beyond ordinary sales functions. Very easy purchase and everything was ready at pick up in perfect order and on time. Very quick process.
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.

Overall Great Truck
I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Thanks for your help! This dealership offered a great deal that I couldn't pass up on. Glad to have worked with them to make this happen. I am particularly appreciative of the no-hassle and no-pressure environment that the salesperson, Cody, did a great job fostering. Looking forward to working with them in the future!

Couldn't be happier with the Boucher team.
Couldn't be happier with the Boucher team. Found the car my wife was looking for on their website at a price that motivated me to purchase the car from out of state and buy a plane ticket to pick it up. My wife arranged the sale over the phone and email. The entire car buying process was made easy by the professionals at Boucher headed up by Mr. Zylka. I flew into Madison and was picked up by "Jim" who really set the bar for the day by picking me up on time, being personable and one of the safest drivers I've ever seen. Once at the dealership I was met by Mr. Hacker who warmly welcomed me and immediately felt like a friend. Throughout the time I spent at Boucher Mr. Hacker exemplified the quality "stellar" he's the kind of guy who doesn't aim for great - he aims to be exemplary. Mr. Hacker ensured I had a place to put my bag and we went to see the car we'd bought. It had been brought into the building and was literally spotless. I bought a 2022 Certified Pre-Owned Cadillac and it looked as if it had just rolled off the line - not even a speck of dust. After seeing the car I was taken to see Mr. Samy the finance manager. I've bought a car or two and this was the part I was expecting some pressure to purchase some additional protection package or have the numbers previously agreed to change somehow. I could not have been more wrong. Mr. Samy made the paperwork end of the process enjoyable. I was offered add ons to the purchase, but all I had to say was "no" and that was the end of it - no pressure whatsoever. All the numbers previously agreed to were accurately reflected on the purchase contract. I thoroughly enjoyed the whole paperwork end of this process and that's because of the friendly attitude and professionalism of Mr. Samy. Once the paperwork was complete, the car was out front and Mr. Hacker took over an hour with me explaining all the new features of the car I was about to drive 16 hours back home. He was knowledgeable, patient and thorough in his explanations. It seems un-needed, but I hadn't ever sat in the driver's seat of a car with all the technology this car has. I don't need to sing the praises of Cadillac - you either appreciate them or you don't. I do sing praises for Boucher Cadillac and I wouldn't do it if I didn't mean it. The place is full of friendly, happy professionals and if you are going to buy a Cadillac, you will enjoy the experience at Boucher Cadillac - even if you buy from out of state and have to drive 16 hours back :)

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.

Had the pleasure of having Nick Majeske provide us with
Had the pleasure of having Nick Majeske provide us with an unbelievable experience of buying a new car. From start to finish and even after we purchased our car, his support and genuine desire to make sure we were satisfied did not go unnoticed. What really stood out to us was throughout the process, Nick was transparent and honest, which I greatly appreciated. He kept us informed every step of the way, and there were no surprises or hidden fees. His professionalism and integrity are truly commendable. We could not be happier with our purchase and overall experience throughout it all, and we would like to think this was in all thanks to Nick.
a great Truck
I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Overall pleasant experience.
Overall pleasant experience. I had some issues arise in the purchasing process, but they were all addressed timely and satisfactorily. Nice people to deal with.
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.

Exceptional and Stress Free Experience!
The service I received was beyond exceptional! Cody in sales took much time to explain all features my suv held. He thoroughly answered all of my questions and made sure all of my expectations were met. He took the time to interact in a fun and relaxing way with my nephew as we waited for financing. Patty in financing was beyond incredible. She went above and beyond to be sure my budget was met and was very understandable and patient! I could have not asked for a better and stress free experience!!
