Customer Testimonials

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.

I had a track day coming up at Laguna Seca and wanted to get some upgrades done to my vehicle to prepare it. I had been travelling and waited until the last minute but Robert was able to accommodate me. Got everything I needed done and saved me a trip by being able to run a track alignment on my vehicle to finish it all off. Robert was able to pull everything together in a matter of days. The service was excellent and the facility was top notch, truly amazing, a built from the ground up complete facility build for servicing Porsche. Truly great service. Would not hesitate to recommend and will take my vehicle there again.
