Used Audi S5 for sale near Boulder, CO

Julia Vargas was very helpful and kind as well! She also seemed very knowledgeable and we appreciate her service very much!

Holy crap....2014 S5 auto very addicting and makes u smile the entire time ur driving. Very quick around town roads. The launch control is remarkable as I never have been beat from cars with more horsepower from a dig. My car ran to 60mph stock and with 105000 miles in 4.6 seconds and 1/4 was 13.1 at 105 mph this was tested my a speed tester box. Weekness is anything over 70 mph to the floor not as quick feeling. Also top end before speed limiter came on was 159. Car will do 175 if removed.

Excellent! I got a great deal and all the sales people were very helpful. It was very nice experience. 1 2 3 4 5 6 7

Love the car only had a coolant pump issue but ever since it's been smooth sailing. The car is gorgeous and incredibly comfortable with beautifully designed interiors. I've drive both the Mercedes c43 Amg and the bmw 340i which I think are this car's competition and I'd still have this as my overall pic.

I have purchased a number of vehicles from this location under different ownership. The one good constant has been the service department and the service tech Dave Singh. Ask for Dave he will not let you down.

Absolutely the most versatile car available. The perfect combination of a sedan, wagon, hatch, and a coupe. The EA839 is a great power plant. Economic all with a great balance of power.

My experience was great from the time I walked in the door, Luke, Mike, and Kelley were fantastic from showing me what they had in my price range to helping me get approved and out the door with a vehicle. Will recommend them to friends and family 100%

Tons of options in great shape. Whether you're shopping for something newer or more budget-conscious, the lot was well-stocked and well-organized.

If you like to drive fast, what something aesthetically beautiful and sleek, but also want something practical and can handle in the snow, this is the perfect car.

Routine service, handled very efficiently, was there for 1.5 hours, pretty quick in my book. Friendly people.

Working with Scott was a real pleasure. My wife and I were surprised at the attention to detail and his willingness to do whatever he could to make the purchase happen.

I hunted the entire country for my SE S5 Prestige Cabriolet Convertible. I had purchased one in Miami, but it was so popular that the dealer re-sold it for an even higher price and issued a refund. The overall design of the car is stunning & the features are everything a Handicapped driver could ever wish for. With the exception of braking; All the controls are right on the steering wheel. During my search, I found 2 for sale in the entire country. 1 was up North in Michigan (snow, ice, & road salt territory) and the other was in Houston Texas. I had it shipped to a local business just off the interstate, where I got my 1st ride in my last car As I do with every vehicle, I made my 10 year old car look like a 3 year old with a change to the newer RS rims, black drilled & slotted rotors and all black chrome emblems. I have made it a sleeper by toning down the flashy appearance but it still draws compliments everywhere I go. The features like the blind spot detection, automatic stabilization, 7 speed dual S-tronic transmission allows incredibly fast shifting or automatic if desired, while alerting you to other cars that are close, or if there is a change in the road conditions. The rear view camera with park assist makes it easy to back up with instant alerts if something enters the area behind. The top can be lowered and raise with the key fob or windows can be opened or closed without even getting in the car. with the top down, there is still plenty of trunk space, and the noise level has been designed to be minimal interference to conversation or music. Handling is a dream and it can be driven with one finger at 100 mph which is unbelievably easy to do without trying. There are 2 things that lowered the reliability rating that, in my opinion, should have been corrected. The harmonic balancer & main dive pulley are 2 pieces, bonded together with rubber. When it comes apart, it shreds the accessory belt and appears to be a clutch pulley to the (even seasoned) mechanic. It still provides plenty of torque to avoid throwing any error code, but it will shred belts until it is replaced, That belt is behind the belt for the turbocharger and the is no clearance between the radiator and the tensioner adjustments to change the belt, unless you put the front end of the car in service mode. The other setback is in the turbocharger iself. The inter-cooler elements themself can crack and leak coolant into he rear cylinders causing a low coolant condition with no evidence of a leak anywhere (mimics a bad head gasket). it would be nice if these 2 crippling conditions were made a little more well known to improve dependability and save a ton of money getting unneeded replacement parts. Overall however; this is the only car that came stock, with all the features I ever wanted and then a couple more. The governor comes on at 165 mph while the speedometer goes to 200 and it is clear that there is more power available. If you were to get racing tires, the computer will remove that limit. I've driven 1000 cars & owned 50 or more & this one is tippy top dog. It is a ton of fun and though plain, remains very attractive and catches everyone's eyes.

We just purchased a Jeep, from Adam in sales, and Kyle in financing, WOW what a team they are! Everything was so easy and fast! So friendly, and knowledgeable?! We are definitely coming back!!!! Thank you!!!!!!!

I can write an entire diatribe about this car but I'll keep it simple! If you are looking for a luxury, convertible, look no further than the S5 cabriolet. I looked at the C43, M440i, this car, IMO, is the BEST value for the money! It is an absolute beast in the performance department, the options that come with this car for the price are unmatched and of course every single detail is perfectly executed!

Top notch Service department. The team that work at Courtesy Mazda knows what customer service is, have great communication skills, and in my situation of having week long mechanical service gave me an awesome complimentary MX5 to drive. The service writer's and manager were both transparent in their process and knew what each other were doing. They got my 2016 Mazda 3 after it sat for 25 days at Caliber Collision collecting snow. They got the mechanical portion done in a timely manner and got me driving my car within a week of inspection, at a lower cost than Caliber was trying to get out of me. I could not be happier with how I was taken care of at Courtesy Mazda. I was told that there is new management in the dealership so I think this is how it is going to be.

Solid sport performance - All seasons - Quality materials, engineering, and design.....definitely a head turner....Exhaust tuning will turn heads..... Best in class! Best in Value!

This thing is stuck on stupid ,gorgeous, in cognito, and such a blast to drive. I scared my father and didn't even have it in stupid mode ! Feel privileged to have this vehicle as a blue collar guy . I'll be buried with it !

Great People and love the atmosphere. Very helpful in any questions we had. Definitely would come back for my future car purchases.

It’s fun to drive ,fast ,smooth ,well build and looks great.just got itv3 days ago. Hope for relatability and look forward to take it on a long trip

Seemless transaction from start to finish on my 2025 Ram Promaster. I?m a contractor and needed a new work van. It was ready just in time for the EOY

Sweet ride and very sporty. Very comfy ride loaded with all the toys. Wish i could have bought the rs model. The car is very quick

I was looking for a specific Ford Truck, a F350 Diesel. I found one on Cars.com that was at Interstate Ford. I live about 2 hours away from the dealership. I contacted Ryan Huber, one of the AMAZING sales reps there, by email. Ryan emailed me within minutes of my inquiry about the truck I saw and made an appointment with my that day to see the truck. Ryan was great! very low key, no nonsense, and helpful. not only did he show me the truck, he helped me through the purchase, financing, and final delivery, coming in on his day off so i could complete the purchase and pick up my NEW TRUCK! Thank you Ryan!! and Thank you Interstate Ford! You folks know about good customer service, valuing my time, and are extremely helpful and knowledgeable! Ryan, you are the best! if you need a new truck or car, Ryan is your guy!

Quick and easy the staff was amazing and lots of car to select from would recommend

This is an S5 convertible and it is a blast to drive. Plenty of power, great interior and is great with the top down. I love Audi's and enjoy driving them.

The guys at Unlimited had just the car I was looking for! As my wife and I approached the car we had our eyes on, we were delighted to see that a dealer had unlocked the car from the remote so we could check it out. Once we were in the car we fell in love with it. As I took it on a test drive I noticed a vibration in the steering and after mentioning it to the team they pulled it into their shop and fixed it on the spot. I am now the happy owner of a Audi A4 Avant Quattro :) Thanks Unlimited for the great experience and a sharp car!

Only reason I’m selling it is because I’m moving to Florida and I would rather have the money. This car has no issues and it’s everything you want from a car and more.

I've driven many makes of quality cars throughout my life and have had many experiences with a multitude of dealers and service centers. Prior to Prestige Audi my best experience was with a Volvo dealer/service center, but the folks at Prestige have exceeded even them. I purchased my Q7 five years ago from Prestige and have had it serviced there ever since - and I have been 100% pleased with those decisions. It's been an extremely reliable car and I've consistently received the best service I could ever hope for, let alone expect. Everyone on the Prestige staff has been very helpful and courteous, but a special shout out goes to Lucas who has been my Service Advisor for most of the past 5 years. I truly couldn't ask for more from any business or individual. 5 Stars and 2 Thumbs Up!

Jay Whittaker did a great job and was very helpful. Walk me through the operation of the car.

Dallas was a great sales guy! No pressure and great service. I bought the car I went to look at and was in and out within one hour. I highly recommend this dealership!

I’ve owned several Audis over the years and my new 2023 S5 Sportback is the best yet Powerful, stylish, reliable, with outstanding build quality Absolutely love this car!

Brice and James were amazing? Best experience ever!
