I recently purchased a car from Ontario Porsche and had an excellent experience. Assisting me in my purchase was Megan Breunig. She was delightful to work with as she was informative, professional and accommodating. The entire experience from start to finish was excellent. DM

Patrick Posie was an excellent sales agent for Porsche Ontario. When first approaching Patrick with my selection of a new car, he listened and led me to a car that was on order and still open for purchase. It was all I wanted and MORE. It did not take me long to go for all the gusto. While the original hopeful delivery date long passed, Patrick kept me well posted on the progress of the car and when it arrived in port. I believe Patrick works hard to be an excellent sales agent.
