They have been doing my q5 service since new. Great experience, was in one day with my dog and met Chris in sales sits right amongst service writers. My buying experience with Chris was excellent.

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.

They have been very professional and helpful. Quality customer service. They offered a full vehicle warranty and full financing.
Beautiful Meh
Leased the car for looks new in 2021. Now 2023 with 28k miles. Perfect? No. Awful? Hardly. Many recalls but no maintenance issues whatsoever. Biggest complaint is the auto-start stop and that the electronics are quirky (pre-set destinations reset frequently) car is comfortable, quiet, quick, and get OK gas mileage (would assume better with 2.0 4cyl.) I often switch between this and a 2017 Honda Accord and to be honest I can't tell much of a difference other than noise and quickness. Will buy it off lease (got it before the residual values rose exponentially) and will keep it indefinitely.

I originally owned an Audi A4, which was an excellent vehicle, very reliable. I expect no less from the A6, which offers all the latest in safety and convenience options. So far I am very pleased with the car and I am only scratching the features it offers. Great ride.

Robin was fantastic! Super friendly, fun to work with, and made the whole process quick and smooth. No pressure, just great vibes and solid help from start to finish. Highly recommend working with Robin if you want an easy, hassle free experience!
Love this car!
Got the premium plus with Executive pkg, black optic and V6. Love this car! Only had it a week, but happy with the purchase. Was originally looking at Mercedes as I had one for 13 years, prior to my Jeep. Price and drivability was superior with the Audi for all the features I wanted.

Best dealership ever!!!
This dealership is the best around!!! We really got an amazing deal and paid way less than the MSRP. Not only that the process was extremely easy. I have two little ones and Mike was able to work with me by getting all the paper work set up before I came in. They also worked on getting me the lowest rate for financing. We ended up getting the Palisades. It is a fantastic SUV with a ton of space and amazing features. I love that it rides like a luxury high end vehicle but didn’t come with the crazy price tag. Overall, this was an amazing experience and I highly recommend them.

We were in the area for a medical procedure & air was slowing leaking from the right back tire. We called the Dealer & they got us right in. They fixed the valve stem which was the problem. They also checked the tires & found we needed 1 new one but would also need a 2nd one soon. We ended up purchasing 2 new tires. Everyone was extremely professional & nice. They sent videos of the repairs as well. This Dealership is superb.

scoured the internet for 2 years to locate the car that I wanted. Kian motors had the car in their inventory. I took a chance and called Layne Elrod at Kian Motors. Right from the onset he treated me as a close friend and not as a salesman. He made sure every question I had was answered to my satisfaction. He was not pushy but wanted to make sure that I got the right car for the right price. The process of buying my car, having it shipped from Texas to Florida, and finalizing the paperwork and payment was very smooth. all because of Layne Elrod. I have seven daughters and when it comes time for their purchase, they will be calling Layne Elrod at Kian Motors first. All the way a pleasurable and stress free experience.
