It could be worse. The Lotus Esprit had Morris Marina door handles.Parts on my Porsche are clearly labeled for other VAG brands. The instrument cluster on my neighbours Seat looks suspiciously alike. Terrible but true.
Famously, the clutch for a Ferrari 246 was the same as one for a Fiat tractor. Same part number, same manufacturer(s). But Fiat agri dealers wanted about £40 or equivalent at some time, and Ferrari wanted £400 for the same parts in a different box.
