Sarah Foster provided EXCELLENT customer service.
Sarah Foster provided EXCELLENT customer service. Everything was ready to go for us upon arrival and the entire process was smooth. After driving from the other side of the state it was refreshing to find the car was as advertised.
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!

Overall customer relationship skills were excellent.
Overall customer relationship skills were excellent. I Bought a used car that was not ready to go when I flew in to pick it up because of a poor inspection. They worked hard get it right. But, it took awhile.
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.

They were fair and responsive.
They were fair and responsive. Answered all questions. Speed of buying experience was best I’ve ever experienced.
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 great certified pre-owned car fully loaded.
This car is amazing. Two of my family members are audi fans so I decided to buy one for myself. Certified pre-owned is definitely the way to go. The interior and exterior are absolutely gorgeous and the ride and comfort is excellent.

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.

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

Shes A6 beauty
Bought this beauty recently and I am kicking myself I did not go Audi sooner! The power is awesome its quiet it rides solid I just love it! I recently got an A7 loaner and did not like it as much as my A6. I love its analog. Only thing to keep in mind sevicing at dealer could be exppensive but I am willing to in order to keep her running! PS I bbought my wife an A4 just given how we are treated at the dealership versus other dealerships!

Thank you Leno and Carboard!
We purchased a 2016 Volvo V60xc with 96k miles on it back in late June of this year. I gotta say, I was a bit nervous buying a used car from a small dealership but Leno and his team were immediately friendly and accommodating. We were looking for this specific model and year of Volvo and felt comfortable with the mileage as this was a local one owner car. Leno provided us with a CarFax report and gave us opportunity to do two test drives. We were already approved for financing with our own bank but we decided to let Leno shop financing and sure enough he beat our bank’s rate by almost a full percentage point with another well known local credit union. The buying experience was super easy and relaxing. We took the car home on a Saturday and all was well for the short drive home. Sunday we took a drive that was our first real test of the car. Much longer than our two test drives that only included a short stretch of freeway from the dealership up one exit to Wadsworth and back. To our horror after a bit of freeway driving we noticed a strange vibration that wasn’t present on the test drives. When we got home I emailed Leno and informed him of the issue. He responded quickly on Monday and asked me to bring the car to their repair shop to have it looked at. I did some research in the meantime and discovered that it was likely a failed U-joint on the driveshaft which only became obvious as the vehicle heated up on a longer drive. My local Volvo mechanic also suggested that as the cause. Sure enough Leon’s technician verified that it was in fact a failed driveshaft. After the diagnosis and to my absolute delight, Leno called to say that he and the owner of the dealership would like to replace the driveshaft at no cost to us. Literally a day and a half later the car was back in our hands driving as good as new. We’re now over a month into owning this car with absolutely no issues since the driveshaft repair. I can’t thank Leno enough. Buying any used car comes with risk, but thanks to Leno and the Carboard team we had a fantastic experience. Thanks again Carboard!
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.
