I been buying cars for over 15 years and this is the best place I ever been thank you so much to jay the manager and Ryan . Jay the manager give me a very good treat even on my work clothes very respectful person.
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!

Friendly staff, polite, listening people who cared about what your needs and aspirations are. I?d recommend this dealer to friends and family. Have purchased 2 vehicles from here and service is great too.
Excellent choice
This is a fun, responsive, reliable, well built car to drive. At over 75K miles now, and I really cannot even consider trading it in because I don't think I will enjoy a better ride.

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.

Very good car eventually
Initially had problems with the front brake rotors. Audi replace them twice, but did not replace the pads. Turned out the pads should have been replaced with the rotors because the pads just transferred material onto the new rotors causing the braking shimmy to return. I paid for new pads on the second rotor replacement - problem solved. Audi could have saved money (and saved me money) by just replacing the pads and rotors the first time. After this, the car was great. Very comfortable, and quick. Gas mileage was very good - about 19 MPG in town and over 30 MPG highway with the 6 -Cyl. due to cylinder cutout when crusing.

A Suprisingly Great Place To Buy A Used Car!
I did a lot of research before visiting Carboard and I ended up purchasing a 2006 Toyota Highlander from them. Leno went the extra mile to get me the lowest APR rate possible and it was low! He really made the effort to do so. There was no "shady sales pressure" to buy like the big dealerships. On the way home the check engine light came on. I let Leno know and he told me to bring it to their service department which is only a few blocks from their lot. It was diagnosed as a faulty catalytic converter and he had it repaired at no cost! He also offers discounts if you use their shop for future repairs. I read some reviews that say they are in a bad part of town. Very untrue. It's on Colfax in an older section of The Denver Metro area but nothing unsafe about it all. I would be comfortable bringing my grandkids there. If you are looking for a great place to buy a used vehicle I highly recommend paying them a visit. Give them a chance, you will not be disappointed!
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.

Will Buy Again.
I bought a Chrysler 300 from levis. A couple years ago. Customer service was great.I compared pricing to other dealerships and the price was on point. The were very transparent on pricing even showing a price comparison of other competitors. Also ,They threw in some custom rims 22in and a second set of when for $500. Car was in sound mechanical condition. Never had a problem with it. Will definitely be buying again.
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.

Buy your dream ride here!
Great Experience! I personally never heard of this place until I walked in the lot. I found the exact vehicle I have been looking for for years. The place is so unbelievably clean. If you’re looking for a unique ride for your next vehicle start here. Save your time going elsewhere. Gabe and Stefan were absolutely fantastic! I’ll recommend anyone I know to buy their vehicles here.
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
