Used Audi S5 for sale near Highland Park, IL

Adulfo at Acura of Westmont delivered outstanding customer service from start to finish. He was professional, patient, and incredibly knowledgeable. Every one of our questions was answered clearly, and he took the time to walk us through all of the technology and features in our new 2026 Acura MDX S so we left fully confident using everything. His attention to detail and genuine care made the entire experience smooth and enjoyable. In addition, the entire staff at Acura of Westmont provided first-class service. This was truly the best dealership experience we’ve had, and I will only buy from Acura of Westmont in the future. I highly recommend working with Adulfo and the team at Acura of Westmont.

Buying my Camaro from Castle Chevrolet in McHenry was an outstanding experience from start to finish. I worked with Eric Loredo, who set the tone by doing a full virtual walk around and video of the car before I arrived, answering all my questions in real time. When my wife and I landed at ORD, the car was spotless and ready to go. Finance Manager Mike Lazzara had all documents sent ahead so I could DocuSign, making the delivery quick and smooth. Sales Manager Matt Knudson, GSM Jerry Spanier, and Andrew Sytsma (who wasn’t my salesman but still took time to chat and share product knowledge) all played a part in making this one of the easiest purchases I’ve ever had. The team knew my previous car was totaled in a tornado, and they went above and beyond to make this out-of-state transaction simple and stress-free. Eric and the entire Castle team reminded me that buying a car doesn’t have to be a battle. I would absolutely buy from them again.

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.

They give you the best price without the hassle. Quick and easy. I’d Definitely recommend.

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!

Great experience. Alex was a charm to work with for the truck I been wanting.

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

Made me feel like family as soon as I walked in very helpful and accommodating to my needs didn?t feel rushed at all great staff and location overall.

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!

The salesperson was very on with the auto I looked at but we couldn’t come together about the price

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.

Glenview was very responsive working with phone calls and texts. They worked hard to get me into the car I had contacted them about.

My experience with Sunset Auto was outstanding. They have a great selection of used cars, all in excellent condition. The sales team was friendly, honest, and very helpful without being pushy. They worked with me to find a car that fit both my needs and my budget. The paperwork process was smooth and quick. Overall, a very professional dealership that truly values customer satisfaction

Great Prices, staff and selection of vehicles to choose from! Thanks Jose for an amazing experience

Fun to drive,very fast and good braking,precise steering,excellent transmission very stable on the road,never had any problem.very reliable,maintenance a bit high compare to others.I would buy another one.

I bought this car for the look & performance (more powerful than the A5). Cockpit layout is fantastic and the craftsmanship is impeccable. Enjoy the ventilated front seats which has kept me cool during the heat of this past summer. Smooth handling and acceleration. #Audi #S5 #Cabriolet #Supercharged

Extremely efficient, polite answered all my questions actually took very good care of me Steven and Casey were wonderful

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.

All around amazing experience at the Auto Showcase of Carol Stream Car Dealership, great people, great selection and even better prices!

Has the comfort for the daily driver but the performance when you want it to enjoy when not in traffic. I wish I could keep this car but must sell as I need a larger car for my growing family.

Worked with John B for a new Bentley. He was quick and efficient, answered all my questions and the car is in mint condition. Car was fully serviced and I love it

I’ve had a half dozen Audi’s including several A4s an A3, A5 and a Q3, but this S5 is closest to perfection. I love the versatility of having a refined four door sedan and a huge opening hatch for my bikes. Then set the drive select to dynamic and you have a fun sports car! My main gripe: the virtual cockpit doesn’t work for me and it was hard to find one with analog dials. Also I didn’t like the new touch screen MMI so I bought an older one. Note to Audi: simpler is better!

I haven’t purchased here, but I’ve been a prospect and they are well priced and very transparent with the vehicle history. They’re also prompt with follow up. The person who posted the fact that they are Ukraine owned has zero impact on them as a business. In fact, the same person posted twice just to damage the ratings. There’s always a dingdong out there.

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.

I had a good experience buying my car from Chicago Cars US. Albert was my salesman, who greeted us with a friendly demeanor. Albert was knowledgeable regarding my car and answered all of our questions. Chicago Cars US staff from Albert, Jacob and Chris were friendly and very professional. I will and have recommended Chicago Cars US to family and friends.

This car is best driven with a manual. too bad Audi dont make them anymore. The performance of the current DCT in them are great, but you are not engage with the beast, you cant replace that with paddle tapping.

Great service experience, all work performed was done accurately. Communication was top notch from Alex Harter. I had no surprises. The dealer exceeded my expectations.

Very accommodating to out-of-town buyers, except pay-in-full is required to hold a vehicle. Need more flexibility on this, like allowing sizable deposit with time limits

Love all of the exterior lines, interior design, and all of the great features wrapped inside of the sexy Audi S5. The performance is top notch. I have owned and liked both Mercedes and BMW, however, I have fallen in love with my Audi. I would love to become an Interior Designer for Audi North America!

I had a very positive experience at Autos of Chicago. The team was friendly, knowledgeable, and took the time to understand what I was looking for. The cars were clean, well-priced, and exactly as advertised. The buying process was quick and straightforward, with no hidden fees or surprises. I’m very happy with my purchase and would highly recommend Autos of Chicago to anyone searching for a trustworthy used car dealer.

Took my son to buy his first car here and it was a fantastic experience from start to finish. Incredibly friendly, helpful, and made the whole process easy and stress-free. They took the time to answer all our questions and made sure my son felt confident and excited about his purchase. Couldn’t have asked for a better first-time car buying experience. Thank you

This car is just flat out fun to drive. Great style and handling and I couldn’t be happier with my purchase. My first Audi and I am really impressed!

Bill was outstanding. Never felt pressured and was very patient. Would highly recommend him for your auto buying needs. Bill takes away all the negative things associated with the car buying process.
