Customer Testimonials

Scott Brown

1969 911E, 1998 Carrera S 3.8 RS

The guys at Patrick Motorsports are the best! Very capable, knowledgeable, friendly and enthusiastic. The quality of their work is top notch. Jim is a Porsche Master......his staff are all professionals as well. They have rare parts and know the air cooled cars very well. They are no slouches with the water cooled cars either. I highly recommend them for all your Porsche needs!

Greg Coon

As I searched for a local shop I kept coming back to PMS. Even though I live in Southern Calif, I called Eric countless times, he was more then happy to educate me on the correct steps to take that worked withen my budget. PMS completed a 911 suspension swap, back dated my bumpers, did some body work and went through my 914 from front to back to make sure I was leaving there shop with a trouble free car. Now that I have my 914 mechanically and cosmetically updated my next step will be a 2.7 swap which will be completed by PMS.
