I took my little Buick Encore there because the check engine light was on. My mechanics name was Nico. He was very informative and responsive. Let me know what was going on through the whole process. These people are great! Reasonably priced. I will absolutely go back there.
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!

3 years with a loaded 2021Yukon Denali deisel
I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

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.
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.

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 inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.

If you are looking for a new car, I would strongly
If you are looking for a new car, I would strongly recommend Willie Boyd at Corwin Toyoya in Boulder, Co. He was attentive, knowledgeable, and went above and beyond to ensure I got the perfect vehicle for my needs. He patiently answered all of my questions, explained the features, and even took the time to demonstrate how everything worked. It was the best car sale experience I have encountered in many decades of purchasing a new car.
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!

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!

My sales agent, Berenisse Miramontes went above and beyond to answer all my questions and remove all of my concerns. By me living out of state and purchasing site unseen Great job 👏
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.

Evan and Lauren was phenomenal. Very easy communication. They made me feel welcome. They understood me and worked with me and went above and beyond. The experience with them 2 was great. These 2 will be memorable to me. I highly recommend to ask for them. I'm thankful to have worked with them 2 only. And I can not forget the front desk employee. She was so sweet.
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 recently purchased a new 2024 Jeep Grand Cherokee
I recently purchased a new 2024 Jeep Grand Cherokee Limited 4x4 from AutoNation Chrysler Jeep Broadway dealership, and I couldn’t be happier! I had a LOT of questions about hybrids, rebates, and leases, but Michael and Chris were incredibly patient and understanding. They never pressured me to decide, providing me with all the information and time I needed to make an informed choice. Although I changed my mind multiple times, ending up with a gas vehicle and then changing vehicles at the last minute, the team remained accommodating. On the day of the sale, Justin went the extra mile to ensure I was set up to utilize all the amazing features and technology. Kevin informed me about warranty and service specials without being pushy - which I appreciated very much! Emily checked in with me before I left to ensure I had a positive experience. Overall, the professionalism, patience, and teamwork displayed at this dealership made my experience a truly positive one. I highly recommend AutoNation Chrysler Jeep Broadway to anyone seeking a customer-centric experience!

Bought a 2011 Outback which had a steering issue, Elijah
Bought a 2011 Outback which had a steering issue, Elijah promised it would be fixed by their service department. It did get fixed, but another issue popped up on the day I came to pick up the car. I couldn't be happier that Elijah caught a maintenance problem twice and told me about it, getting it fixed without passing the buck or pretending it didn't happen. Top-tier, above and beyond service. The sales process itself was one of the fastest and smoothest I've ever experienced, and although I'm frustrated that I still can't drive my car home, I'm immensely relieved that the staff at Autonation are taking care of it with integrity and professionalism.

I bought my car at Holman Honda. My car alerted me that my tire pressures were low. I went to the service area and Delon checked my tire pressure, added air, and calibrated it and the alert disappeared. 1 week later the same thing happened and this time Paul did the same thing. I have been driving my car over a week and the alert has not come back. Delon and Paul provided excellent customer service. They both went above and beyond to help me. Keep up the excellent work!

I didn't buy the most expensive car on the lot, but you would never know it by the way Austin Roper gave me executive treatment! From the moment I walked in the door I was treated like the most important customer the dealership has. I was given a GREAT deal and FANTASTIC service by everybody at the dealership.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!
