Specialization
Porsche Restoration, Modification, Backdating or OEM Plus restomods - Not everyone can do everything
The market for Porsche® 911® restoration, backdating and individualization is characterized by exorbitantly high prices, long waiting lists, workshops and dealers with dubious customer orientation and reliability.
Separating the wheat from the chaff in this scene and making the right decisions, from the right choice of model to the right choice of partner, requires a lot of experience and paid tuition, an excellent network and consistent customer orientation.
We founded PrinzipR to close this gap.
