I came to interstate Ford to have a recall issue taken
I came to interstate Ford to have a recall issue taken care of. Mary Jo Fuletti helped me with that problem. I told her that there were other concerns regarding my F150 truck. She listened to my concerns and translated them so that her mechanical staff would understand what needed to be looked at. After an inspection, I was informed that there was about $5000 worth of work to be done. I have a Toyota warranty for the vehicle having bought it used from a Toyota dealer. Mary Jo had difficulty getting a response from the warranty folks but she was tenacious and got an inspector from the warranty office to come look at the truck and approve the work that needed to be done. Through Mary Joe’s and interstate Fords efforts, I had a total of about $6000 worth of work done with no out-of-pocket charges. I will definitely be back when my truck needs service or work. They have earned my respect and trust. I’m

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Always a pleasure to get my truck serviced at Mike
Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

This team worked to find everything that I wanted in a vehicle. They located it on the other side of Denver and delivered it to the lot closest to me on the next business day. The sales and finance team worked with me to get terms that I was comfortable with paying on a monthly basis, as well as an overall price driving off the lot. This is my second purchase of a vehicle with the AutoNation Team at different locations and they always work hard to be helpful and fair.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

GREAT VALUE - GREAT SERVICE - GREAT TRUCK
HONEST Abe owns and runs this dealership and is not your stereotypical used car guy. He makes promises and keeps them. He took care of the finer elements of a used truck purchase by making sure everything worked and looked good before we took it home. He also referred me to his audio guy and assured that I received excellent service at an excellent price. I got more than a used truck with Truck Kings, I also got access to their network of trusted professionals to modify and maintain it. I will buy my next truck from Abe again.

Excellent experience
After reading all the good reviews of Courtesy, decided to buy a CX-9 here. The staff was friendly, well-versed on the features of the car, and arranged two test drives without any hassle at all. The obvious honesty in everything they did stood out, including Dave, Amy and the sales manager (Brian?). It was a pleasant experience. The buying process was relatively fast and painless. I also talked to several customers who were waiting for their cars in the service area, and they had nothing but good things to say too.
Best Truck I ever owned!
This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!
