About PRDesignsf


Our background

 We are car enthusiasts who love classic automobiles. Our crew consists of an engineer, product designer and auto technicians. Classic and vintage cars are no strangers to us, as well as modern automobiles. We especially love BMWs and other classics. Our goal is to try to help these classics live a longer life with replacement parts that are no longer available. With what we do, we can keep these automobiles on the road and helping the community.


What we do

PR Designsf is an affiliate company of Auto Dynamik, Inc. (autodynamiksf.com) in the San Francisco area, who have been servicing San Franciscans and the neighborhood since 1987. Due to increasing demand on these classic automobiles, we discovered many parts have become no longer available over time. To make the job easier and help other enthusiasts, we started designing parts that are no longer available or try to improve the function of existing components. Currently, we are primarily concentrating on the BMW 2002's heater box components. We also work on other products for different automobiles. Using our own product design to repair or service our client automobiles, we believe that we can make an improvement to what's currently out on the market.
