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.

It was time to move on from our 2002 Oldsmobile after 20 years. It’s been that long since I’ve been to a car dealership or even test drove a newer vehicle so I had little a trepidation about purchasing a new vehicle. I did my research and decided that I wanted a 2024 Hyundai Tuscan hybrid. I cannot express how painless the process was- no pressure. Dakota, our salesperson, is incredibly knowledgeable, patient, and perceptive. The service staff is professional and approachable. Financing was smooth and efficient. The inventory is impressive but if Boucher doesn’t have what you’re looking for I’m sure they can find it. We both are very happy.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

I had an outstanding experience working with Ty on my recent vehicle purchase. He was consistently responsive, knowledgeable, and never pushy throughout the process. We don’t purchase new vehicles often, but when the time comes again, I will certainly return to Ty. I highly recommend him to anyone looking for a straightforward and positive buying experience.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

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?

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

Our trusted dealer/repair shop for over a decade!
We have been customers of Reina's service department for well over a decade where Lorenzo and his team have done wonderful work on our vehicles. Because of our trust in Lorenzo, when it came time to buy a car 10 years ago, it was on his advice that we chose the type of car we were seeking. Once we knew what we wanted Filipo and Joe went out and found us exactly what we wanted as it wasn't on the lot at the time. I am happy to say that car is still on the road, being driven daily, and serving us well. We have since purchased 2 more cars, including one just yesterday, and couldn't be happier with the service and attention to detail the whole team there gives us everytime we walk through the door.
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

SMOOTHEST, MOST HONEST DEAL EVER MADE FOR A WOMAN!
MICHAL MADE THE SHOPPING AND BUYING PROCESS SO EASY AND NOT SCARY AT ALL. I AM PRETTY xxxx PROUD OF MYSELF FOR PURCHASING A VEHICLE ALL BY MYSELF AND NOT REGRETTING IT! I BELIEVE THAT MICHAL WAS SINCERE AND HONEST IN GETTING THE VERY BEST DEAL AND DOING ALL HE POSSIBLY COULD TO GET EVERYTHING THAT I ASKED FOR. ANDY IN FINANCE WENT ABOVE AND BEYOND TO WORK THINGS OUT IN MY BEST INTEREST FOR CAR PAYMENTS AND ALL OF THE EXTRAS. HE WAS A JOY TO WORK WITH AND VERY PROFESSIONAL AT THE SAME TIME. I FELT LIKE I WAS IN THE VERY BEST HANDS WITH THE BOTH OF THESE GUYS AND IT WAS ALMOST TOO GOOD TO BE TRUE. WE'LL SEE... BUT FOR ME. THIS WAS A PERFECT EXPERIENCE AND I WOULD RECOMMEND HALL VW AND MICHAL AND ANDY IN A HEARTBEAT!

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

I had a great experience working with Jason Archimede from start to finish. I wanted to upgrade from a sedan to a 3rd row SUV and he took the time to ask questions and listen to what was important to me in a vehicle. I did not have a specific vehicle in mind when I began my search so I appreciate all his time, effort, and flexibility to help me find what was right for me. He is very knowledgeable and I absolutely recommend working with Jason. I have nothing but great things to say about Jason and the staff at Boucher Nissan I met among the way. Thanks Jason!

What an easy and smooth transaction. I can't say enough good things about the dealership and staff. Knowledgeable, professional, helpful.
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’ve always received great service at this location. Dominic and Mike were extremely courteous and helpful in helping me navigate my end of lease options. Highly recommend stopping in and doing business with Boucher Hyundai of Waukesha!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I purchased a new Jeep Wrangler Rubicon X from Uptown. The entire experience was incredibly positive. There was no pressure. My trade in value was fair. Overall I was very pleased with my purchase and the process of buying the vehicle.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.
