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.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Love this place and definitely recommend Alan Roque, the best worker there is definitely 5 starts.
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.

Great experience
I had a light come on that concerned me and Doug at Mcdonald VW helped me get my car in right away. They even give a LYFT credit so I could get home. Within 48 hours I had a video of the technician going through what they found, what they fixed, and even did an oil change and checked tires too just so everything was perfect. All under warranty so no charge to me and these are some of the nicest guys at this place. I see some negative reviews and I really think sometimes people create their own problems, like declining a recall and then being upset? This place is great and they are even renovating to have a really nice new building.
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!

Working with Berenisse in the purchase of the car I was
Working with Berenisse in the purchase of the car I was wanting was an awesome and pleasurable experience. She was not only very knowledgeable but a treat to communicate with and made the whole experience wonderful. If you are looking to purchase a vehicle from Sharpest Rides I recommend working with her hands down. It was my pleasure to work with her.
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.

Emick's has been servicing our vehicles for many years
Emick's has been servicing our vehicles for many years and has managed to keep them on the road and running well. The Service Dept. is efficient and professional.
Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

As a woman, walking into a car dealership can often feel
As a woman, walking into a car dealership can often feel like walking into a trap where you?re not heard, not respected, and often taken advantage of. Sadly, that?s been my reality in the past. But today, Autonation Subaru changed everything. From the moment I stepped through the doors, I knew this wasn?t your typical dealership. Bruno, Dylan, Brian, and Syed created an atmosphere that felt relaxed, respectful, and empowering. They genuinely listened to me. They met me where I was?honoring my budget, my needs, and my wants without pressure, gimmicks, or condescension. I never once felt like I was being ?sold to.? Instead, I felt like I was in control of my own car-buying journey. The level of professionalism, transparency, and integrity shown by this Subaru dealership is unmatched. I walked in with anxiety and doubt, and left with total confidence and a Subaru Forester that I?m absolutely in love with. Because of this experience, I?m a customer for life. If you?re a woman looking for a dealership that actually respects you (or honestly, if you?re anyone who wants a fair, human-first experience) go to Autonation Subaru. They?ve set a new standard for what buying a car should feel like.

Great experience
Brandon West worked with us for the purchase of a 2021 Kona EV. He was very accomodating and professional about addressing any of our issues and has followed up several times after the purchase to make sure we are happy. He is very responsive to our follow up questions. We have found that the Kona EV is a perfect little car for running aorund town at a cost of around 2.5 cents a mile if one is buying electricity at $0.12/kWh. It sure drives like a little rocket compared out our other IC car
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Great experience with this dealer and David our salesman. They are top notch. Also had great service from Steve in parts in purchasing a back seat protector for our new Forester. I wish we could use their service department but live too far away. Well run dealership. Thank you.
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 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.
Reliable.
It met all of my needs, it drives well and is easy to maneuver for its size. I would recommend this vehicle for anybody who needs a full-size vehicle.

5 Stars for Jake Conner at Echo Park Automotive -
5 Stars for Jake Conner at Echo Park Automotive - Centennial, CO! Jake Conner at Echo Park Automotive (10401 East Arapahoe Road, Centennial, CO) was outstanding! From the moment we walked in, Jake gave us his full attention and made the entire car-buying experience genuinely enjoyable. As we all know, buying a car can be a long and sometimes stressful process—but that wasn’t the case here. Jake made everything smooth, fun, and stress-free. His professionalism, patience, and personable attitude really stood out. We felt taken care of from start to finish. I’d absolutely recommend Jake to anyone in the market for a vehicle, and I’ll definitely be back when it’s time for our next car. Thanks, Jake!

They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable.
