I found Porsche Ontario while looking for a 911 but unlike many dealers who were not helpful or overly pushy, Carlos Raez stuck a balance of informative and helpful. He did not push me to take a test drive but accommodated my tight schedule. Not your typical dealership experience!

Jose Martinez (my sales person) was a good guy and helped me get to a fair price on my trade in and new vehicle. Keep up the good work...

I've been a service client here for a few years, and have always had a 5-Star Experience. I just finished my first purchase at Porsche Ontario today (including a trade); and Jhovan Coronado and his team bent over backwards to make the process smooth and stress free. From getting me the highest value for my outgoing vehicle, to offering the best price on my new 2024 Cayenne Turbo GT, the entire staff were there to help. If you're in the market for a P-Car, I can't recommend them enough!!!

Got my 2024 GT3RS!! The General Manager Mark is an admirable gentleman who keeps his promises and takes care of his customers. Thank you for the valuable gift by the way. I‘’m sure this young porsche dealership will get a remarkable achievement under his leadership in the near future. And for our brand ambassador Prismo, who shows consistent professional during each of our purchase. Its been tough to stand between the clients and the supervisor,which is a test for every sales person, but Prismo handles a butcher's cleaver skillfully.

We never thought buying a Porsche would be so much fun! And that is all thank to Patrick Posey! The whole experience was stress free and we couldn’t be more thrilled with the outstanding service he provided throughout our entire purchasing journey. From the moment we stepped into the dealership, we were welcomed by Patrick who is super nice, friendly, polite, patience, professional and knowledgeable! Patrick’s attentiveness was extraordinary. We were very indecisive between the models, we wanted to know how many luggage would fit into the Cayenne’s trunk and here comes Patrick! who is wonderfully accommodating, ...
