Was very pleased with my car buying experience with Walter’s Mercedes-Benz of Riverside. I think it was a fair price for the vehicle, but the real standout was my salesperson. Rafael was very polite and professional and really made the whole process great. -Adam D.

I had a great experience working with Jason Cai on my new Cayenne S Coupe in Chalk, which is also my first Porsche.

I had such a great experience purchasing my daughter’s first car with Manny Pavon! From the very beginning, Manny was incredibly kind, patient, knowledgeable, and helpful throughout the entire process. Buying a car is a big decision, and Manny really went above and beyond to make sure we all felt confident and taken care of from start to finish. We absolutely love the new car and couldn’t be happier with the experience. Thank you so much, Manny and Porsche Ontario!
Had a great experience working with Jason Cai! He was professional, knowledgeable, responsive, and made the entire Porsche buying process smooth and straightforward.
Carlos Rayez Is great to deal with. I’m a repeat customer even if the dealership isn’t physically close to me. He’s professional, easy to deal with, quick to respond, and I know I’m getting a great car with him. I’d highly recommend Porsche Ontario and Carlos Rayez for an easy and professional transaction.
I’ve purchased various cars at various dealerships but never was inclined to leave a review one way or another. With Porsche Ontario though, I felt I had to.
I was interested in a Cayman and browsed numerous sites trying to find “my one”. Porsche Ontario had one that met my criteria the only issue was the distance. I called the dealership and asked for availability and I was transferred to Manny Pavon. I asked if there was anyway to make a FaceTime appointment so I can view the car. I thought he’d say either no or set a ... Read More

I am extremely happy that Jason Cai helped me with my 911 purchase—his professionalism and patience truly made a wonderful impression on me. Thank you, Jason, for making the entire experience so great!
I've always had a good experience with this service center. I worked with Ralph Perez with my windshield replacement. He's a solid guy. Honest, helpful and trustworthy. It's never fun to have to pay for a windshield replacement, but these guys did a great job.
Denise Galaviz was a pleasure to work with. She made us feel comfortable by listening to our concerns and made sure I walked away with a deal we are happy with. I love my Q6 Etron Premium Plus and enjoy driving it. Go see Denise😊

Anthony was the sales rep who greeted and took care of me from beginning to end. He listened to my unique situation, and went out of his way to make the deal work for me. Thank you brother. Ethan is the manager, and Chris the finance guy both helped me make today a great day to shop car. Thank you very much for the amazing shopping experience at Audi Riverside, and the beautiful M340i now sitting pretty inside my garage. 😎
Shawn is very knowledgeable about every car at the Audi dealership. He made the experience very quick and easy! He answered all of my questions and was an expert about every detail on the car.

I had an outstanding experience with Porsche Riverside from beginning to end. Buying a car can be stressful, but the entire team made the process smooth, enjoyable, and truly first-class.

Raymond Garcia did a great job from the first email to the final delivery of our 718 Cayman. He always had great follow up and even answered emails/texts after normal working hours.

I had a wonderful experience at Porsche Ontario. We stopped by to look at cars and was greeted by Sha Peng. He was very pleasant and showed us the car we were interested in. Then when we talked numbers he was diligent in getting us the best price. He did not pressure us at all. We met the manager Pouya and he was also fantastic. The buying process is such a pleasant experience. I highly recommend asking for Sha Peng for your next Porsche.
I highly recommend Eddy. He’s honest, quick to the point and will do his absolute best to get you the best deal! I was referred to him by someone else ,whom I highly respect. I proceeded to contacted Eddy, stopped by the dealership, and within 30 minutes I had already signed on a new and great lease option. No tricks, no fluff, no nonsense. If you are looking for a Mercedes, whether you live in Riverside or not, Eddy is your guy!
I have been working with Audi Ontario since I bought my A4 years ago. Sometimes it’s not about buying the new car but more about customer service and knowledge. I have not dealt with a single person at this dealer from service to sales to the management team that’s doesn’t know what they’re doing. Dealers take notes this is what customer service looks like at all levels. When a dealer can tell you hey man take some time think it over instead of predatorily preying on your want for a new car.

We bought a $125,000 car and we can't get a second key. They gave us a non-working key, believed to have been swapped with another vehicle. We also cannot access the online system because there is another user they have to remove. I am rather notorious for losing keys so this is important to us. My husband has made numerous calls and absolutely nothing has been done. It's been months. Excuse after excuse. Salesperson, useless. Manager, useless. All they have to do is get us a working key. Simple. The purchase itself was fine. But when you walk out ... Read More

I stopped by Porsche Riverside without an appointment, and as soon as I got out of my car, I ran into Jason Cai at the front door. Looking back, I’m really glad I did.
I honestly didn’t expect to end up buying a 911 GTS so quickly. I always thought I’d probably have to wait a long time, maybe even close to a year, to get the one I wanted. Jason made the whole process much easier than I expected and kept everything moving smoothly.

I am a new client to this particular dealership. I have 2 Audi’s and they were always serviced at the Sister dealer in Ontario. I finally decided to try the Riverside dealer and found them to be off the charts. I needed items from the parts department and the gentleman who helped me was so friendly and kind. We laughed and talked like old friends. And now, I can trust the Riverside store just like I have trusted and relied on the Ontario store. Being kind goes a long ways. Thank you Walter’s Audi for years of great service.

I decided to take my R8 to Audi Ontario for an oil change, since it is close to my work. After a couple of days since I picked up my car from your dealership, the low engine oil light has come on. Needless to say, I am very disappointed in the service I have received.
The oil change is WAY overpriced at over $1,200 (in comparison, my oil change last year at Audi North OC was $550.) And that is just for an oil change; no other maintenance items like fluids, etc. For an oil change at that price, it is inexcusable ... Read More
