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!

I passed by auto express shopping for a luxury vehicle
I passed by auto express shopping for a luxury vehicle and had the opportunity to work with Marc. I’m glad I didn’t waste time going somewhere else. This place is real and the cars are nice!!
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!

We leased a RXH and we’re fortunate to have Reda Tabriz as our salesperson. He is extremely knowledgeable and always returned phone calls promptly. Buying a new car is usually stressful, however he made the process very smooth. Based on our experience I would recommend this dealership.

Juan Cabreja Salesperson
Mr. Cabreja was professional when we got upset that the vehicle we wanted to purchase was sold and tried to advise us that he was willing to assist us to find the vehicle we wanted. He did find the vehicle and a couple of days later we drove it home. He was attentive to our needs and very caring, as if, he was a family member.
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.

Only place i would buy my car
Amazing manager and team! Super trustworthy place. Great deals and great price! Thanks John for your time and your help in finding me the right car!
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.

Amazing service and so helpful!!
Richard is an incredible car dealer. I had to unexpectedly get a new car and wasn’t prepared for the process because I didn’t plan on it. But he helped me through every step of the way. I hit some bumps in the car buying road, but Richard was incredibly helpful throughout the process and helped me get the best deal possible. I recommend Reliable Auto Sales to everyone!
Most Reliable Car I Have Owned
Love the way it drives and no problems whatsoever. Owned it for 3 years. Very comfortable and great in snow with cold weather package for heated steering wheel, etc. Great ride!

We found this deal on cars.com and the car was available. Other dealers we visited did not have the car and had large fees. We're glad we found this place. Thanks to Anthony and Gina for all their help.

You won’t regret buying this car!!
I’ve had the 2014 A6 TDI for theee months now and absolutely love it. I average about 33 city and 40 plus on long trips. Very comfortable, quiet, and feels so solid. Even closing the door, you can tell it is so well built by how heavy the doors are! I hope to be writing another review in 150k miles!!
