Worked with Christian Agraso to order a new Porsche Taycan and the experience was excellent. From start to finish Christian was always there to answer any questions I had and keep me updated throughout the process. Any accommodations I needed were happily full-filled by Christian and the team. When the day came to pickup the car the entire experience was simple and seamless.

What a wonderful experience from A-Z working Patrick Posey and the team. White Glove treatment. I was will informed on the progress and process of my build which took 7 months to arrive. Very thorough and professional the whole way through. Picking up the car was also an experience and such an enjoyable process that I will always remember. The integrity and heritage of Porsche starts with the customer's interaction with their dealership and Ontario Porsche delivered A+.
