⭐⭐⭐⭐⭐ Exceptional Service from Joel at The Sharpest
⭐⭐⭐⭐⭐ Exceptional Service from Joel at The Sharpest Rides! I had an outstanding experience working with Joel at The Sharpest Rides in Englewood, CO. From the moment I walked in, Joel was professional, knowledgeable, and genuinely invested in helping me find the right vehicle. He made the entire process smooth, stress-free, and even enjoyable—which is rare when buying a car! Joel answered all my questions with patience and honesty, and there was never any pressure. He went above and beyond to make sure I got a great deal and was happy with my purchase. I truly appreciated his transparency and dedication to customer satisfaction. If you’re in the market for a used car and want top-notch service, ask for Joel—you won’t be disappointed
Pure luxury
This Audi is beautiful, inside and out, with genuine wood in the door panels, dash and center console, soft leather seats, and a massive amount of red light illumination throughout the front cockpit, that is fantastic while driving at night. The exterior is sleek and stylish. The ride is smooth, however the low profile tires do ruin some of the ride atleast on kansas roads that are far from smooth. The engine has no vibrations and suspension seems tight . All in all this is as close to perfection as it gets, German cars are the best.

Great experience all around
Working with Scott was a real pleasure. My wife and I were surprised at the attention to detail and his willingness to do whatever he could to make the purchase happen.
Must buy at a realistic price.
Such a gorgeous vehicle, inside and out. Haven’t had a single issue with it for over a year of having it used. Inside of the vehicle is super roomy, and driving feels very comfortable, and really we’ll insulated!

Amazing & Professional Crew
Recently bought a used car here ~ I went to get the car's emissions test done right after I drove it off the lot & it failed the emissions test due to the check engine light suddenly coming on. I took the car back ~ they identified the problem. They said, "We WILL fix this." Not only did they order a new part for the car ~ THEY took the car for the emissions test ~ they loaned me a car to get back & forth to work. My car passed the emissions test straightaway ~ and they had my car ready for me to pick up LESS than 24 hours from the beginning of of this issue. Ralph & his crew are truly AMAZING! If you're in the market for a car ~ please check this place out! You won't regret it!
So fun to drive
The new design is awesome. The size of the car is perfect. Leges room is so good and the screens in the dashboard looks fantastic

My husband and I were so overwhelmed with our car search
My husband and I were so overwhelmed with our car search and were worried coming here may be just one more example of the sleazy used car salesman trope--we could not have been more wrong!! Joseph listened attentively to what mattered most to us in functionality, comfort, and price, and helped us to find many options that would be a good fit for us. We had a list of some we were interested in and he recommended some others that would fit the ticket well. He was so patient and informative as we test drove countless cars! Seriously, this guy is like a walking car encyclopedia! But also, isn't afraid to look something up if he's not sure, which rarely happens. It felt like car shopping with your cool uncle who knows everything about cars and is looking out for you. Can't recommend enough asking for Joseph when you need your next car!! He can pull almost any car from another Autonation location, so it's worth going here to work with him even if it's out of your way or doesn't have the car you think you might want! We wound up not finding our vehicle within the Autonation inventory, but still wanted to go out of our way to leave a review for Joseph because he made that much of an impact! A great ally in the stressful, overwhelming process of a big purchase :)

Great Used Dealership
We came all the way from Fort Collins,Co. Got great deal on Nissan Frontier 2006. Well be back to this Dealership for the next one first!
Quattro Manual Fun
Quattro holds the corners like no other car I have driven hard! 2.0T tuned to 300hp with a manual transmission is just fun. No deed to get the S model. But may want the avant wagon A4 for the family or even A6.

Great People and love the atmosphere. Very helpful in any questions we had. Definitely would come back for my future car purchases.
My favorite car out of the over 17 that I’ve owned
An truly amazing car with the best technology I have ever seen in an automobile. I am an electrical engineer so I don’t make that claim lightly. The best engineered car I have ever owned. I look forward to driving it whenever I need to go somewhere - a powerful comfortable car that can compete with cars costing much more.

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.
Perfect sports sedan, TDI engine is amazing!
Bought my '16 A6 3.0 TDI a year ago with 89k miles, now has almost 110k miles, and drives like a dream still. Can't even tell it's a diesel engine by the way it drives and how quiet it is. I drive a lot for work, and the gas mileage is amazing! Interior is comfy, classy, and roomy. Drives like butter, handles like a sports car. Exterior isn't too flashy, it's perfect. No issues, and my last checkup at the German export dealer was perfect. My favorite car I've owned, now I want an A8 L!

All Around Excellent!
Best dealership in town. Second vehicle purchased with no hustle and easy precise transaction. From visit to post sale follow up, excellent. Great selection of vehicles, and cool place to see some unique rides.
2004 Audi A6 2.7T S-Line my first love
I owned a 04 a6 and absolutely loved it. Very reliable and a blast to drive in the winter. Car has just enough power and decent gas mpg if you drive civil. Lol. Highly recommend. I will say if you don't have money for the maintenance forget it. These cars are beautiful machines and are expensive to work on. Absolutely worth it tho. I bought it certified preowned from the Audi Exchange and I'll never buy another brand. Bought to buy another one

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!
My 5th Audi
I still have an RS4, but I love my A6 3.2. 245K miles, replaced the MMI, battery, alternator,... Perfect in the Lake Placid winter. The RS is a beast, but the A6 is a workhorse.

Highly recommended dealership
I reside in Arizona and bought a used 2016 M4 out of state from this dealership in Colorado and Chad Folkerts-whom I strongly recommend-,my sales rep, did an incredible job coordinating the entire process. I flew out for a test drive and walk around of the vehicle prior to signing and Chad was personable, professional, and had great communication both on the phone and in-person. I even made him jump hoops by having it pre inspected at the local BMW dealership. Also helped arrange getting the car shipped down here. I also had a great experience with Roman, their finance manager. He made signing quick and painless. I applaud the level of customer service at this dealership!
