Since Christopher R. Moore founded it in 1997, Autobahn Extremist has built its identity around a singular passion for Porsche and direct involvement from its owner. The Brooklyn Heights shop serves every generation of the marque, from the 356 through the 991, with work kept under one roof and a TUV-inspired practice of checking each car for safety concerns during service. Its restoration work has produced Parade-winning concours Porsches.
