I was initially delighted.
I was initially delighted. The sales staff was awesome and got me into a dream car. Three days after bringing my Redeye home I noticed a small puddle of antifreeze. Two days later the engine light comes on so I had it towed back to the dealership and told them to keep it until they get it right. This is day five. I would still recommend this dealership as long as you buy new. Evidently I bought a Frankenstein. I just hope that this is a one off and am able to enjoy the car for years to come.

I was interested in a new GMC Acadia, specific features
I was interested in a new GMC Acadia, specific features and model. Zac Taylor worked very hard to bring a vehicle from the Colorado Springs store. He had everything outfitted as needed, worked out details remotely, then delivered it to me in the mountains. I drove away a great new vehicle at an outstanding price point. Thank you Zac for all of your hard work during this car purchase!
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.

It was a very good experience.
It was a very good experience. The personnel there are friendly and helpful and create a very comfortable atmosphere that would be highly appreciative of anyone interested in buying a car. They give options without being too suggestive and respect the customers decision. If I could give some advise, I would always provide 2 sets of keys to the customer. I only got one and I feel like I should not have to deal with going somewhere else to buy a spare in case of something happening to the original key. The customers down payment should allow for 2 keys.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Absolutely incredible from start to finish. Online purchase of a 2025 Ford F-150 Tremor was a relaxing and unemotional event thanks to Christina. From the trade-in value negotiation to finalizing a very fair price point, my experience was enjoyable. I will return to Auto Nation Ford Littleton!!

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.

Awesome experience.
Awesome experience. My husband and I looked at practically every mid size SUV Known to man. Of all the dealerships we visited and all the sales personell we met (including two other far substandard VW dealerships), McDonalds VW ranked #1! The most respectful and helpful sales personell! Tanner and Atticus were both polished, kind, patient, and highly intelligent in their sales positions. I had come to accept that I would have to settle for a VW package that wasn’t quite what I wanted, but Tanner saved the day and delivered (within 24 hours) with my dream car!! Cory (finance manager) worked very hard and truly went above and beyond to earn our business. What an amazing group!! Would highly recommend!!!
The best deal 4me my dream truck it's mine if poss
I want this truck if I can't get help with finances I'll try againfri and ill have cash. I want it 100percent I've only dreamed of owning a truck like this and now if the Good Lord willing and the creek don't rise.a dream might come true.,!!!!!! I love everything about this ride.just rite for the open road.

I love this dealership way way underpriced best quality awesome selection even better staff it's funny even the reception is unlike other dealerships the reception is for this dealership actually had car knowledge which was very exciting because if the receptionist knew what was going on with automobiles I could only imagine how great this whole sales team is again thanks for making everything so streamlined
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.

Initially I dealt with Dan, the owner, over the internet.
Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan

We had a great experience with this dealership!
We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

Matt Wise and the rest of the John Elway team were all professional and very helpful in every aspect, in the purchase of our new Chevy traverse. We recommend anyone looking for a new vehicle go to John Elway on South Broadway. Again, Thank You ALL!!!!
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

Super Satisfied
I recently purchased a truck from SAG Denver, I have had a very positive and professional experience with the sales and service departments. I normally avoid dealerships at all costs, however I came across a beautiful truck that I was having difficulty finding on the private market. I enquired online and was replied to very expediently. I received a no pressure call from a sales person who scheduled an appointment with me. When I arrived, I was greeted and assisted immediately. I test drove the truck with Tracey, who by the way, I highly recommend working with. After driving and inspecting the truck for a bit, I detected what is a common mechanical problem with that type of truck. I brought it up to Tracey and the sales manager Dan and my concerns were immediately acknowledged and validated. Dan did not try to gloss over my concern or argue that there was an issue, instead, he gracefully offered to have the repairs made along with any other contributing or resulting damage as needed. I left the truck with them to begin the repairs, unfortunately it was a bit more involved than originally thought. There ended up being a significant amount of engine work needed, nothing that could have possibly been detectable without opening up the motor. I think most dealerships would have somehow tried to find a way to charge me or unwind the deal rather than proceed with completing all necessary repairs and making the truck run properly. I have several other vehicles so I wasn't by any means inconvenienced, however I did purchase the truck because I had to haul some things for family. After the repairs ran into an extended period of time I did email to express my concerns, I received a call from Dan offering me another truck from their inventory until the repairs were completed on mine. I can't express enough how impressed and pleased I am with the entire experience with Springs Automotive in Denver, I would definitely recommend them and would buy from them again.

Our two Mazdas were total losses due to the Hailstorm
Our two Mazdas were total losses due to the Hailstorm that struck Cheyenne WY on August 1, 2025. I found AutoSearch USA through cars.com and contacted them about a Mazda CX-5 the had listed. Mike Blunn was great! They had just listed the car the previous Friday, and still needed top get some prep work done, but we set up a date to see it the following Tuesday. The car was not quite ready for us to take that day, so we made arrangements to meet at an Enterprise location midway between Cheyenne WY and AutoSeach USA's location so we could finalize the sale and turn in our rental. Everything went off without a hitch. I highly recommended AutoSearch USA for anyone looking for quality car buying experience.
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!
