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!

A few weeks ago I purchased a used car at McGrath Acura
A few weeks ago I purchased a used car at McGrath Acura in Libertyville and wanted to share my experience. When I arrived I was greeted by Ethan Sevilla. Ethan was enthusiastic and knowledgeable, and understood just what I was looking for. From beginning to end Ethan explained every detail and answered all my questions. In just a short time I was banging the GONG in the showroom! The entire staff was pleasant and professional. I felt comfortable and was treated fairly. Thanks again to Ethan and the McGrath family.

I recently purchased a car here, and Dan made the car-buying process quick and easy. He was honest, attentive, and helpful every step of the way. I bought a highly special used car, and Dan's knowledge and guidance made me feel confident throughout the process. I'm very happy with my new car and the service I received. I would definitely recommend Dan and this dealership to anyone in the market for a vehicle.

Very friendly staff that helped me find the right car and sent me up with financing that worked for me. I appreciate the time they took to explain the process and made everything really easy! Definitely my place to go when i need another new car in the future.
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.

"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.

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.

Every staff member we interacted with was helpful, courteous and professional. Buying a vehicle from Seann Omara was particularly wonderful— he is knowledgeable, helpful, and genuinely committed to making sure we got the best deal possible. We left very pleased and would happily recommend Napleton Buick GMC to others!

I just bought my 2017 corvette grand sport two weeks ago. I flew in from New York. I can’t say enough good things about the process. We worked with Armin, he was top notch. He made every aspect about buying this car seamless and easy. He even arranged an Uber to pick me up from the airport to bring me right to the dealership. We just adore our new car. It’s perfect!! A million thanks 🙂 Joe and Denise

We recently purchased a car from Your Choice Autos, and the entire experience was genuinely outstanding from start to finish. From the moment we walked in, we felt welcomed and taken care of. Our salesman was incredibly informative, and attentive to everything we said or asked. He took the time to really listen to our needs, answered every question thoroughly, and made sure we understood each step of the process. What stood out most was how smoothly everything went. There was no pressure, no confusion—just honest guidance and a clear commitment to helping us find the right vehicle. He made the entire experience feel easy and stress-free, which is something we truly appreciate when making such a big purchase. We wouldn’t hesitate to recommend them to anyone looking for a quality vehicle and a dealership that truly puts its customers first.

I had an outstanding experience with Eryk Buczynski at Castle Volkswagen of Schaumburg. From the moment I walked in, Eryk was incredibly welcoming, knowledgeable, and genuinely focused on helping me find the perfect vehicle. He took the time to listen to my needs, answered all my questions with patience, and provided clear, transparent information about pricing, options, and financing. What stood out most was Eryk’s dedication to ensuring I felt comfortable and confident with my decision. He guided me through the features of the car, demonstrated how everything worked, and followed up afterward to make sure I was enjoying my new vehicle. The entire process was smooth, efficient, and stress-free. If you’re shopping for a new or used vehicle in the Schaumburg area, I highly recommend asking for Eryk. His professionalism, integrity, and customer-first approach truly set him apart. Castle Volkswagen of Schaumburg is fortunate to have him on the team. Thank you, Eryk, for a fantastic car-buying experience!
