We were traveling through Colorado and wanted to buy a new F350. We called on a Wednesday morning. Mo, the salesman who answered the phone, agreed to meet with us that afternoon when we arrived. We left before evening dinnertime, having purchased exactly the truck we wanted for a fair price. Outstanding.
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!
There all reliable it’s red & beautiful

Brilliant Car, expert servicing
Excellent car, just done 122K and runs like a dream, had it serviced regular by brilliant guys at the general motor company in Stockport in UK. Didn't want to trade in when lease finished. Looking to get many more miles Peter Gilligan

Better than my first Audi
I have owned this car for just over a year. No mechanical problems, very fun to drive. Took it across the country, very comfortable for driver and passenger. Loves to cruise at 75-85 mph and will go much faster. I thought I got a great deal on it. I paid half the sticker price and it had under 10,000 miles on it.

2005 Chevy Tahoe
Excellent staff and great customer service would definitely return for another vehicle. The one I bought was clean and in excellent condition. I definitely see my family having it for a while.
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.

Fantastic Experience End-to-end
I wish I could give 6 stars. Annu Achar worked with me on a purchase of a used Subaru Outback. I am out of state and found the car online. Annu was prompt, professional and attentive through the entire process, which took nearly a month by the time the vehicle got to my doorstep. Annu even worked through an unplanned trip to the hospital. Annu responded immediately to my initial inquiry, went to bat for me early on pricing, secured the vehicle so that it was reserved for me, promptly addressed some paperwork preferences I had, arranged for the car to be shipped, again went to bat for me when I requested a late change in price, and assured that the car was taken care of in transport. I asked a lot of Annu in this transaction and he came through each and every time. Thank you Annu! Fantastic performance!
Very nice upscale vehicle. Bought as a previously
Very nice upscale vehicle. Bought as a previously 2 yr leased auto, avoiding new car price and immediate depreciation. V-6 engine has no hesitation and quietness is excellent. My only two negatives are lack of storage for incidentals and a bit quirky audio that may reset from time to time ( must wait for it to go through a cycle). It has a mind of its own. Overall, excellent vehicle.

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.

Awesome buying experience
Very good buying experience. We purchased a BMW with the help of Phil. Both Phil and the rest of the staff were always very friendly throughout the buying process and we never felt pressured to buy the vehicle. We were able to test drive the car by ourself and more than one time before buying.
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

Just a update regarding my last rating and review, after a meeting with the owner Ali Awada. He took care of me and paid for my car repair and gave me 100.00 for my family and I to have dinner. Thanks Colorado Auto Finders for doing your best to make things right for with me.
A lot of fun to drive
Very reliable family sedan that is also fun to drive. The quatro (All wheel drive) is very help full on winter roads in the mountain. Roomy comfortable interior with ample room for adults in the back seat as well. Like the bluetooth to stream music, Pandora etc. Hands free phone connection.

I recently bought my teen's first car from this
I recently bought my teen's first car from this dealership, and I had such a positive experience! I was looking for an affordable price point with the best mileage and reliability for a young driver. Brandon and Leon were incredibly helpful, patient, and transparent throughout the entire process. As a woman, buying a car at a dealership can sometimes feel intimidating, but I never felt rushed or pushed. They made everything easy and straightforward. I truly felt like they had my back, and most importantly—my teen ended up with the perfect car for what I was looking for. Highly recommend working with them if you're looking for honesty, kindness, and a smooth buying experience!
A6 2003 experience
‘03 Audi A6, reliable and great in snow. Timing belt & water pump leaks at 65k, no other major repairs needed. Easy to drive 550 miles/day cross-country. Good lumbar adjustments & cruise control 👍
