[QUOTE 1814412, member: 45"]I think it's the Hillman Imp that is famously said to have been put together using whichever parts were to hand in the nearest bin, and so had many ad-hoc variants.[/quote]
The Moto Guzzi V50 was similar. A MkIII could have MkII bits and MkI but the next MkIII could have entirely different MKII components. Getting parts was a nightmare and I had to return quite a few bits to the dealer as they were not entirely compatible with the fitting used for the component that they were replacing.
