Used 2018 Audi S5 for Sale in Ontario, CA

I have really enjoyed the 2018 S5 Sportback. Great car with comfort, power, safety features, and cutting edge technology. This is overall the most competent car I’ve ever owned. Have over 17k on it right now. No problems at all and the only slight complaint I have is the fact I’ll have to replace the tires soon. I’ll just change from the Continental tires with no mileage warranty to Michelin tires with a 30k warranty. Hey, but what do you expect with a car that will run high 12’s from the factory. Would definitely recommend.

How can you describe a car that can do zero to sixty in 4.4 seconds yet achieve 35 MPG at 70 mph, and do this in absolute luxury? Let’s include a 19-speaker Bang and Olufsen sound system to crank out your tunes at any sound level. Want to find anything at the touch of a finger? Then get the Audi Connect feature and the world around you is at the command of your voice and the touch of you finger. This gorgeous Audi is far ahead of its time. Are you?

Nice car inside out, powerful engine, nice handling, the transmission trashed the car and all the good work. Be aware the transmission performance deteriorates with time, feels like a torque converter slip, lag in shifts, and unnecessary upshift, slow shifter as well. Navigation lacks street names - stereo keeps going to default settings - gas mileage not close to promised due to transmission - excessive brakes dust - voice command was better in the 2017 s5 - rear cupholder useless- transmission can be reset and then few weeks later gradually same issue. Anyone that reviewed the car drove it like a race car where its hard to notice - car drives awful on a stop and go especially when the auto engine shutoff keeps turning the motor off and then you have 3k RPM takeoff to keep up with a minivan, driving normal is very frustrating - Very SAD

I bought my 2017 A3 from another local dealer, and found their service department to be a little frustrating to contend with, so I brought the car to Audi of Ontario. Right from the start, I found this dealership very easy to work with. Erik Garcia is my service advisor, and he is probably the best advisor I've had across several brands. He listens to what I tell him, he relates to the issue and how it impacts his customer, and he makes sure to follow up in a very timely manner. I have a solid understanding of the mechanics of a car, and Erik understood that he had to relate to me differently than some other customers. He has conversations with me that are not so elementary that they don't tell me anything, and not so advanced for me to not understand. He put the effort in to pay attention to my level of knowledge so that it didn't become frustrating to me. Shortly after one visit, I received an email that the dealership was interested in buying my car. I was surprised as it was a lease, and I was only 14 months in. I met with Raymundo Lopez who was absolutely terrific to work with. He explained the process he wanted to follow to me, which put me at great ease. I generally do not like the schmoozy sales experience, but there was none of that. He was up front, honest, and timely. I took this opportunity to upgrade, and Raymundo was extremely patient as I looked at many different situations that would work for me. We looked at everything from another A3 to an A5, to a TT. In the end, I walked away with a fully decked out A4 Quattro that I absolutely LOVE!!! It cost a little more than I planned, but I'm good with it. And when you think about it, isn't that the true sales success story? Customer is happy and gets something they love, the dealer sold something of higher value. I cannot say enough good things about my experience with Erik and with Raymundo. The terrific experience in the service department lead to a really great (and unexpected) sales experience. I would highly recommend Erik Garcia for all of your service needs, and Raymundo Lopez for all of your sales needs!! A quick follow-up.....I have personalized plates, and had to go through the arduous DMV process of waiting for the new registration to get processed, then transfer the vanity plates over. The DMV has a new process regarding this, requiring permission from the leasing company to do this. I called Raymundo, and he started making calls to find out what to do. This happened several weeks after the sale, which further exemplified his professionalism. He did not push me off because the sales was done, he went all out. THAT is the great experience you can expect from Raymundo!! I will add that the billing guy was the only shortcoming through all of this. Not "bad" per se, just not great. His personality was lackluster, and when he tried to push the extra warranty on me, and I refused, he tried an angle I did NOT like at all.....he used the line "well, if you think you want to take a risk like that, it's your choice". I don't do passive-aggressive, and was not happy about that AT ALL. But.....in the end, I have a great car that I love, and overall, a terrific experience that I tell everyone I can about. It is my feeling that since he is responsible for processing all of the paperwork, including the registration, he should have known about this vanity plate requirement, and explained it to me. That way, I wouldn't have had the added stress of finding out about it, and dealing with it while at the DMV. That, I believe, is a major fail on his part. I would recommend both of these gentlemen to care for your Audi needs. They are the best, and I will definitely be back :)

Beautifully styled. Solid build with plenty of technology and amenities. But, the bottom line is that this car is fun to drive, safe and confidence inspiring. Happy, happy, happy!

We had been looking for a used 2018 Audi Q5 for some time and had run into too many poorly run dealerships that simply did not listen to what we wanted in our area. Once we expanded our search, we found Marcos Morales at Walter's Audi in Riverside who went SO FAR BEYOND what any salesperson has done in the past. He was AMAZING start to finish and truly understands that this is a SERVICE oriented business and you have to LISTEN to what the customer wants, not TELL them. He did a personalized video of the vehicle we were interested in. He answered EVERY question we had in a quick and courteous fashion. He was professional and LISTENED (note to other dealerships we did NOT buy from: YOU listen to US, not the other way around!) to our needs, and we drove over 350 miles to get this car, bypassing a lot of dealerships along the way! Just a great experience buying a car from Walter's Audi and Marcos Morales.

Fun car, super responsive, fast, tons of power , elegant, designed very well as a driving machine with great look in mind. My red seats are gorgeous, and the engine power is unmatched. I owned near 100 cars in my lifetime, and this is my baby! I simply love it.

Have owned Mercedes, BMW, Audi and VW. My S5 seems to be the perfect car for me. Right size, gorgeous styling, and very responsive. Everything I need, plus some

I was looking for a 2 door coupe. Drove the Audi S5, Lexus and Mercedes. S5 wins hands down, better performance and handling and looks on the S5 at a better price. The back seat is tight on the S5, but no different then the other coupes I drove. Beautiful, quiet interior and great stereo too. Only complaint is cup holders can only handle smaller cups.
