My service rep, David Barron, was excellent...again. I've had the pleasure of working with David since I switched my Porsche 2016 Boxster Spyder servicing to Porsche Ontario. He has gone above and beyond expectations.

I very much enjoyed my car-buying experience at Ontario Porsche. Although a bit far from my home, it was worth the drive. JB was very patient with me, answered all my questions, and allowed me to take my time with the test drive and examination of the car. JB is very knowledgable and passionate about the brand, and was able to honestly answer my questions - and never acted like a pushy salesman. I also enjoyed working with Mike in the finance department. I would highly recommend this dealership for your Porsche buying needs.
