Ralphs has a new shop

In 2015 Ralph's moved to a new shop! This was an exciting time for us, and our new shop is located only 2 units down from our old facility. This close move makes reaching us easy for our customers, and gives us more than three times the shop space!

Upcoming Events

We are happy to be able to partner with many well known Porsche enthusiast groups, such as the Porsche Club of America, Chesapeake Region. Partnerships such as this allow us to grow as a community while expanding the network of Baltimore area Porsche owners. If you are not already a member of an organization such as the P.C.A., we highly recommend joining! By doing so you will be able to stay up to date on local and national Porsche events.

Come and see us after Hunt Valley Horsepower on most sunny Saturdays! Contact Us for more information.

    With over 40 years experience in Porsche service and repair. Our automobiles have included everything from national concourse winning 356's to race cars and the latest offerings from Porsche. Ralph Simmers began His automotive career with Porsche at the age of 21 with Stuttgart Import Corporation Towson, MD.

    This was the very first Porsche dealer in the Baltimore area. Ralph was fortunate to crew as mechanic for various race teams, including Bruce "King Carrera" Jennings and the fabled Toad Hall Racing during the 1969, 1970, and 1971 campaigns at Sebring and Daytona. Ralph's Auto Service opened as an independent Porsche shop in 1971. We take pride in servicing everything Porsche, including 356 Speedsters, 356 A/B/C, 912, 911, 911 Turbo, 914, 914-6, 924, 944, 944 Turbo, 968, 964, 993, 996, Boxsters and Caymans.

    We also provide detailed preparation for vintage rallies, track days, and competition motorsports. We have grown over the years through hard work, courteous service, honesty and impeccable quality that only five decades of experience can deliver.


    As of 2015 we are operating out of a new shop, conveniently located right next to our old one. With over three times more shop space, we are happy to announce the addition of 3 new, fulltime mehanics to our staff. Our new faciliies boast 6 new lifts, a designated machine shop, office space, and a comfortably furninshed waiting room. We are also currently the only independent shop in the 5-state region to have an ultrasonic parts clearner. This expansion has occured in order to help keep up with the growing demand for quality indepenent Porsche service in the greater Baltimore area.
