There was a legal battle over a Bentley a few years ago. It had a good racing history and as a result it had been rebuilt, parts changed etc as a consequence of the normal racing repair and maintenance.The woman who bought it subsequently tried claiming a mis-selling as she thought the “originality” described was untrue due to many replacements , including engine. She lost her case in the High Court as the changes were documented and were the norm for a racing car.
If that's Brewer v Mann she won.
