Brandon was amazing! Was easiest car buying process ever! Will definitely return and highly recommended! Thanks! Do yourselves a favor and go to McDonald Hyundai!
"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.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Lifelong customer
If I could rate my experience with 100 stars I would! This dealership does not pay on commission which made the whole experience less stressful and they have a great inventory along with a great staff. My husband and I went to this dealership because they had all the vehicles I was interested in test driving. When we arrived we were greeted by Vanessa. Let me tell you how lucky we were to have her. She is so caring, enthusiastic, took pride in her work and was never pushy. Once we narrowed it down to purchasing a 2021 Ford bronco she was very thorough in explaining everthing as we went through the paperwork and options. I feel like I gained a friend after working with Vanessa. Even after I bought the bronco she continued to text me to make sure everything was alright and even mailed us a thank you card, which I greatly appreciated. Then during our purchase, we were blessed with Tyler who jumped in to help. He knew everything about broncos and sat with us for over an hour pointing out the different features and answering my 5 million questions. He also assisted us in getting the ford pass app set up on our phone. I highly recommend this dealership to anyone whether you are interested in buying or still trying to determine what you want to buy! Thank you again to Vanessa and Tyler for all your help, guidance and providing us with outstanding customer service. You have gained a life long customer. Mishala & Steve

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

My wonderful car buying experience
I was very pleased with the vehicle I was able to purchase at Grand Valley Auto Lakewood! I had less than perfect credit after being left carless in my divorce. My friends had recently purchased a car from Mike and Kelley and they assured me I would be treated honestly and fairly. I was very skeptical due to the fact that I had recently been taken advantage of on the purchase of my new TV. They listened to my wants and needs and I left in a car that I both loved and knew would do the job. I would definitely recommend and return for my next vehicle purchase!
