New and used 2025 Audi Q4 e-tron for sale near Diamond Bar, CA

Walter’s Audi is great!! Romen Artalejo helped me every step of the way and was very thorough in explaining the perks of the car and the entire financing process. I came in a few days before Christmas and needed more time to think about the purchase, Romen was understanding and supportive about my need to wait. When I came back the day after Christmas Romen was readily available again to help me get the car of my dreams. He is very courteous and professional, making the whole process seamless! Definitely purchasing my next Audi from Walter’s again!

If you are planning to contact the sales team of Walter's Audi and you need to pick a guy to work with choose Romen Artalejo. He will assist you in every way he can, he is sincere, polite, honest, very communicative and will work with you to make it happen. As an out of state buyer I recently bought an high end car from this dealership and Romen did a 5 star job and I am very pleased and highly recommend him as your salesmen at Walter's Audi

I had an excellent experience leasing my new Audi Q3 from Audi Ontario, thanks to Farzy Rashid. From the moment I walked in, Farzy was incredibly helpful, professional, and attentive to my needs. He made the entire leasing process seamless and stress-free. The Audi Q3 is a fantastic vehicle—stylish, comfortable, and packed with all the latest technology. Farzy helped me navigate through all the options and made sure I got the absolute best deal possible. I couldn't be happier with my new car and the exceptional service I received. It would not have been possible without Farzy's help and expertise! Highly recommend working with Farzy if you're considering leasing or purchasing an Audi. Thanks again, Farzy!

Taylor was friendly and helpful, offered several options and a fantastic deal on the Q3 I selected. He also worked around my tight schedule. I love my new car. Thanks!

Great job from Freddy Lopez from start to finish. I felt accommodated in all aspects by him. He had great knowledge and was very informative during the process.

Anthony Lee did a great job for us when buying our new Audi S8. Quick comfortable process and experience

Nice team, car was good - had some concerns about tires, windshield and CPO warranty. Decided to continue my search for now.

Excellent customer service. I'm treated very well every time I visit. Waiting area is very comfortable. Daryl (service manager) is great. Kept me informed of everything while I waited.

I had a lot of questions. Emerson Molina sat with me for as long as I needed to help me understand the maintenance needed and put together a strategy to help manage costs.

Gabriel the salesman was professional and low key. Helped bridge the gap with Management and get a deal done.

I had such a a WONDERFUL experience at this dealership with salesman Majid. He put me in a car that was a perfect match for me. I've purchased new cars in the past and I must say this one was the best experience by far. The entire process was seamless. The guys in the finance office were also very helpful in explaining any questions I had. I was very excited to drive my new car off the lot. I can honestly say Majid was just as excited and happy for me as I was for myself. Thank you again Majid and Lexus of Cerritos!
