This was my second year in a row doing business with
This was my second year in a row doing business with AutoNationUSA-Katy, and it turned out to be even better than the first year. Our salesperson, Jeremiah Ragona, was personable, extremely knowledgeable, and (according to my grandson) even fun to spend time with. The car I ultimately picked to purchase was a bit of an unexpected choice, but one that my wife was quite happy with. Big ups to Jeremiah and the AutoNationUSA-Katy team for a very satifying car-buying experience.

Best car I've ever owned, best value too!
I bought my 2013 S6 used with 121k Mi in 2019 from a dodge stealership for $21k. At that price I knew something was wrong, but took the gamble. To my delight, it was only a coolant leak that the Audi stealership fixed for about a grand. In the +23K miles that I've put on it, I've only had to replace breaks, front wheel hub, and control arms, which is expected at that mileage. I've never been left stranded. I've upgraded the ECU and TCU software and have lowered the car using VCDS, and none of that has given me any issues, only increased driving enjoyment. Then after a month of owning it, my GF discovered that my front seats have built in massage! I've owned 2 Audis before this and a dozen other cars, and I have to say this is my favorite by a huge margin, and an excellent value. It really is the prefect blend of comfort and performance. I just got the parts to convert to E85, will be adding near another 80HP and paying a $ a gallon less for fuel, couldn't be happier! Now it's paid off, I can spend $ on upgrades and get the handling on par with other high performance sedans in it's segment.

Great buying experience. Vehicle was well priced and the service was great. Trade in value was fair. Sales staff was knowledgeable and friendly. Facility was fair at best.
Sophisticated Performance Sedan
I purchased the 2021 Audi S6 Prestige after looking at similar vehicles in the class like the BMW M550i and Mercedes Benz AMG E53. My choice came down to performance, reliability, look, and value. I have had the car for 4 weeks and have no regrets. My highway gas mileage has been as high as 31 miles per gallon which is terrific for a car with this type of performance. The controls are easy to learn and the car feels like it is floating when driving it. I like that it is a performance vehicle with an understated look. Some may want a car with a more aggressive look but I like the understated, traditional sedan look. So far I would recommend this car.

Truly special car
I have owned a number of Audi cars and this is by far the best I have driven. It is very quiet and smooth and the acceleration is the best aspect of the car. I purchased it used with low mileage and it is a great value. This car will be memorable.

Our Salesman Ata was absolutely amazing! He was attentive, respectful, and helpful without being pushy or aggressive. We explained to him exactly what we were looking for and the budget we needed to stay within, and he "MADE" it happen for us. Best Car buying experience my wife and I have had in several years. Highly recommend Ata and Lone Star Cadillac!

Will return for service
Had a recall and lube/oil/filter service, which all went well. My only interaction was with Joel, and he has a great attitude and provided excellent customer service.
This car is legitimately cool
It?s comfortable, modern, fast, and handles well. Definitely no regrets in buying one. If you?re on the fence about which Audi to get, spend the extra money and get the S6.

The best Audi Dealership
I only work with Audi South Coast. The entire team is focused on relationships, not transactions like other Dealers. Most dealerships have a bad name for ripping off the customers, trying sneak in fees to trick the customer. Not at Audi South Coast. My sales advisor Ben Kazanjian was wonderful. We have become personal friends. Derek Dicker the Sales manager is the god of cars, a true enthusiast that knows everything about Audis. Christopher Childs another Sales Manager made my deal happen. Another person focused on relationships and taking care of the customer. Sammi Ly the General Sales Manager is the queen of finance. She went above and beyond to make the numbers works. I go out of my way to send them customers for a reason. I highly recommend Penske Audi South Coast

Perfect balance of performance, comfort and luxury
You can really have fun with this car. Drive on rails, takes sharp turns at high speed effortlessly. The acceleration can be mind numbing, especially with Launch Control. Mine was well equipped (e.g. perf package, massage and ventilated seats, etc.) so it made it even more enjoyable. It's quiet and comfy when you want it to, like driving the family around, and you can wake up the beast for some personal fun on the track, empty canyon roads or highway ramps.

Top Dealer in Dallas
One of the best dealer in country Owner is a nice guy knowledgeable and honest person I bought a car and well satisfied, He really helped me with all inventory and explained all details to me. Thanks Hamid
Most enjoyable car I’ve ever owned.
My S6 might be the most enjoyable car that I have ever owned. I’ve been Ver fortunate In life, fortunate enough to own and/or drive many nice, high end vehicles. Ferrari, Lambo’s, Lotus, Mercedes, BMW, Jaguar, Porsche, Land Rover, etc. this by far is my favorite. The car is very comfortable but it doesn’t stop with there. They have taken a very comfortable and easy to drive car and made it into a true sleeper. This car is a rocket, it’s actually almost too fast if that’s possible. Yes, it’s not flashy like a Testa Rosa. It’s not as recognizable as a 911 turbo and not quite as refined as an S600 or a V12 Vanden Plas, but wow, it will seriously blow your socks off. I never imagined that a mid sized 4 door sedan would be so much fun to drive. I can fit the kids, car seats included, the golf clubs, wife and dog and I still believe it 0-60 in under 4 sec. comfort, ridiculous power, all wheel drive and room, what’s not to love.

They were very prompt, polite and professional. Very low pressure. A very good experience. I would recommend.
This is a great car.
This is a great car. Purchased new, and still performs as new. It is a smooth pavement pounder and you will or may find you'll exceed posted limits without realizing or "feeling" the speed. Boost lets you pass with confidence. Now, concerning service; owning an AUDI requires regular maintenance and replacement of components that fail with use. This can be expensive. Keep in mind these vehicles are performance oriented. Our S6 was outfitted with all features and none have failed us as yet. The expense of upkeep is a warning to those considering purchasing a used vehicle, do your due diligence. A poorly serviced vehicle will lead to a problematic experience. Often demoted by steep depreciation.
