About Us

Porsche Ontario is one of the newest Porsche Centers in Southern California. As part of the Walter’s Automotive Group, it continues to provide the award-winning customer service. The Walter Automotive Group has a long-standing history of excellent customer service, but it all has stemmed from the year 1948, when Walter Kienle emigrated to the U.S. from Switzerland. After several years working as an auto mechanic, serving in the U.S. Army, and opening and managing an automotive garage, Walter eventually settled in Riverside in 1960, where he established Walter’s Automotive Service with an emphasis on European cars.

I had a wonderful time during my test drive with Shelly Fisher. He was an outstanding brand ambassador: enthusiastic, professional, and genuinely passionate about the cars he represents. You can feel his energy and pride when he introduces a vehicle, and it makes the whole experience more memorable. He was welcoming, patient, and incredibly kind throughout the visit. I also want to highlight how exceptional he was with my case for the CPO 2024 Carrera S. The morning after I asked about the car’s availability on CarGurus, he personally sent me a detailed video walk-around of the vehicle. No other dealer or brand ambassador I’ve spoken with has ever done that for me. That level of initiative and care made a huge difference and showed how committed he is to helping customers.

Dealer did not want to take a deposit, then sold the car. I offered to put 50% down and agreed to asking price, but needed to make arrangements prior to flying out. He refused then sold the car without reaching out to me.

I'm Mark Marchant, General Manager at Porsche Ontario and I want to personally apologize for your disappointing experience with us.

I'm genuinely concerned about how your situation was handled. A customer offering 50% down and agreeing to our asking price while making travel arrangements should have received much better service. This doesn't reflect our dealership's standards, and I take full responsibility for this breakdown. Without knowing more specifics about your interaction, I can't address exactly what happened, but I am committed to investigating this matter thoroughly. I'd apprecia

Went there to look at a car I saw on their website. They told me the car was in the shop with minor paint repairs. They said to come back in the afternoon at 3pm the following day. Needless to say I called them a few hours the next day, about 2pm. They said the vehicle was already sold in the morning. No call, no advanced notice they were going to sell it. I don’t mind that they sold it, but don’t lie and said it would return in the afternoon when it was sold in the morning. Dishonest sales people. Otherwise they have a nice showroom.

Hi Alan,

I’m so sorry that this was your experience here and I can completely understand why you are upset.  With just your first name here it’s a bit tough to locate your records without doing some more digging but I wanted to respond as quickly as I could.  Could you please call me so I can learn more about what happened and with whom you were working with here?  I’d also like to be able to extend a sincere apology for this.

This dealership is a busy one, based on the vehicles they get I am sure they have a lot of request to get to. Their sales assistants are awesome, they stepped up to the plate while the actual sales reps where busy helping other customers. They had a vehicle that I was interested in, but the price a little too high for my current budget (and it was missing a couple of key options). They seem like a good company to do business with...

Porsche Ontario had offered a 2015 Porsche Boxster Cobalt Blue with about 26279miles for sale. I contacted dealership . Jhovan Coronado was the person who sent me information. He was very helpful about the car. He had ready fro me to test drive. I had overall a good experience with the driving this Porsche Boxster. I had a trade which was appraised by car max. Jhovan had their appraiser evaluate my MB SLK350, and offered a reasonable price for trade. The sale part was not too difficult, their finance team was just as good and went extra mile for a good rate. Overall I would recommend this dealership, their pricing was competitive with overall market.
