VIN Decoder & Registry

Decode the VIN. Preserve the story. Build the registry.

PetrolJunky is a VIN decoder and registry for classic BMW, Porsche, Volkswagen, Mercedes-Benz, MG, Datsun, Triumph, Austin-Healey, Jaguar, Alfa Romeo, Toyota and Ferrari chassis numbers plus modern 17-character VINs. Decode the car first, then preserve photographs, ownership history and the details that make its story worth keeping.

Decode privately. Share when you’re ready. Nothing is added to the Public Registry unless an owner or contributor chooses to share it.
