We have been servicing Porsche since I first began unloading them off the Baltimore docks in 1968. We have 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.

I began my automotive career with Porsche at the age of 18 with Stuttgart Import Corporation in Towson, MD. This was the very first Porsche dealer in the Baltimore area. I 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 pre-A's, 356 A/B/C, 912, 911, 911 Turbo, 914, 914-6, 924, 944, 944 Turbo, 968, 964, 993, 996, Boxsters and Caymans. Your Porsche will serviced by certified Porsche Master Technicians using OEM parts whenever possible. 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.

I look forward to the privilege of servicing your fine Porsche automobile.
