  Classic automobiles are an important part of the automotive industry and
represent the historical and technological achievements of certain eras.
However, to be considered masterpieces, they must be maintained in pristine
condition or restored according to strict guidelines applied by expert
services. Therefore, all data about restoration processes and other relevant
information about these vehicles must be rigorously documented to ensure their
verifiability and immutability. Here, we report on our ongoing research to
adequately provide such capabilities to the classic car ecosystem.
  Using a design science research approach, we have developed a
blockchain-based solution using Hyperledger Fabric that facilitates the proper
recording of classic car information, restoration procedures applied, and all
related documentation by ensuring that this data is immutable and trustworthy
while promoting collaboration between interested parties. This solution was
validated and received positive feedback from various entities in the classic
car sector. The enhanced and secured documentation is expected to contribute to
the digital transformation of the classic car sector, promote authenticity and
trustworthiness, and ultimately increase the market value of classic cars.
