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!

Reuben DelaCruz Lube Express Advisor at Lithia Dodge 4313 S. Staples. He is very courteous and patient with me and all customers. He is the only employee that has stayed with Lithia Dodge. He has worked at the car company for a long time.
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!

Had an appointment with a sales consultant. He was very helpful and patient with my questions. I did not purchase from him - it was about the car, not the sales consultant.
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 called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

My buying experience was simple, helpful and flawless. Oswaldo was a pleasure to work with.
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.

Today we purchased a 2023 Ford edge.
Today we purchased a 2023 Ford edge. I definitely would recommend buying a vehicle from them. They go above and beyond to get you the best deal. Jimmy and Heidi were fantastic to work with. They are very helpful and such a pleasure to do business with making buying a vehicle stress free. Jimmy did a fantastic job with our deal!!! Thank you to Mike George as well working with Jimmy on our deal.
Reliable and comfortable.
I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Experience buying my new Ford Ranger at Germain Ford was very good. Salesman Jean wasextremely nice to work with. Had a little delivery delay due to a part recall, but other than that, experience was fine. I ansolutely love the Ranger compared to my Honda Ridgeline!!!!!!
Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

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

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 went to multiple car dealerships and each time I spoke
I went to multiple car dealerships and each time I spoke with a sales person and set the parameters of what I was looking for and my budget, everything I said was disregarded and at one location they quoted a lease payment of $219.00 per month and when I went in to see the vehicle, the price changed to $419.00 per month!! On the verge of giving up and just keeping what I had, I looked one more time on line and saw a vehicle I was interested in. I sent an inquiry in to Mohawk Honda and that's where everything changed!! A saleswoman named Amanda text me and asked a convenient time to call (which I appreciated because I work during the day). We ended up texting and I advised her of my price range and what type of car I was looking for and within an hour she sent me two leads on vehicles and included the warrantee information, the car fax, the service records and photographs! She answered every question honestly and always with my best interest in mind. When I said I was interested in one of the vehicles, she asked me to send photographs of my trade in, along with the registration information. Within one hour, I had a reasonable offer for my trade in and we made an appointment to look at the car the following day. I arrived early and she was ready!! She sat and went over all the information and got the car for me to test drive. I asked about one concern about the vehicle and she immediately said she would have the mechanics look over my concern. The car is beautiful and was everything Amanda described and promised. We went in to do the paperwork and there was no wasting of my time, she helped me transfer insurance, get the pay off on the trade in, went over the new vehicles information and I spent less than two hours to seal the deal. Every other dealership had me there for almost four hours and to be honest, with lots of empty promises. I have NEVER had this great an experience at a car dealership, where it felt like they had MY best interest in mind foremost. I liked that my interaction commenced with Amanda and then I was able to continue to work with her through the closing. She is absolutely down to earth, considerate and quite amazing. I watched the entire team of salespeople interact and they were all so helpful to each other, and genuinely friendly and happy. I never said "I have a Car Dealership" before, but I do consider them my Car Dealership and would start and end every vehicle search with them. How refreshing to have an experience like I had with Mohawk Honda. And for the other Dealerships that were a dissappointment...you could learn alot about how to conduct business by watching them! They are doing it right!!!

Had a great salesman in Vinny. I had hardly any waiting around at all. Will go back in 3 yr for next suv.
Exceptional truck with one annoying detail.
I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.
