Kyle was amazing. He was knowledgeable and never pushy. He knew when to give us information on the cars and when to let us talk about it. His years of experience show and he's a pleasure to work with! Go Echo!

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.

Julia was awesome! We were unsure of what we could qualify for or what we wanted, but with her patience and understanding we found something that fit us and our budget. The finance team was super and got me a surprisingly great monthly payment. Will return for the next car!
Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

I just wanted to thank Rob for getting me out of a difficult jamb. My battery was failing, which required multiple jumps, and Rob was able to get me into service immediately even though his schedule was quite full. Rob had the battery replaced within 30 minutes of my arrival. I have never visited Fowler dealership in the past but will make it my go to place for future services.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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.
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

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!

The experience was great. Auto Nation was able to put me in a Jeep that I wanted and take care of my leased Jeep that I bought back. The process went smoothly and I was completely satisfied. I recommend Auto Nation for purchasing your next vehicle.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Awesome experience!
I was looking for a specific Ford Truck, a F350 Diesel. I found one on Cars.com that was at Interstate Ford. I live about 2 hours away from the dealership. I contacted Ryan Huber, one of the AMAZING sales reps there, by email. Ryan emailed me within minutes of my inquiry about the truck I saw and made an appointment with my that day to see the truck. Ryan was great! very low key, no nonsense, and helpful. not only did he show me the truck, he helped me through the purchase, financing, and final delivery, coming in on his day off so i could complete the purchase and pick up my NEW TRUCK! Thank you Ryan!! and Thank you Interstate Ford! You folks know about good customer service, valuing my time, and are extremely helpful and knowledgeable! Ryan, you are the best! if you need a new truck or car, Ryan is your guy!
I have enjoyed my vehicle.

Chris at Interstate Ford was absolutely amazing. He searched his inventory for a vehicle that I could afford. I would shop there again!
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.

Subaru sales, service, parts, and finance department
Subaru sales, service, parts, and finance department staff at AutoNation Subaru West in Golden, Colorado were polite, friendly, competent, and professional. Purchase process on our 2025 WRX was pleasant and straightforward. We encountered no dealer markup on the purchase of our new car: instead, we received an automatic dealer discount without asking for it.
Favorite car I have owned, to date!
The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

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!

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.
