Although no longer ours, a MK1 we formerly owned was recently stolen in the Ripley area of Surrey,early on a Sunday morning.
It's registration Nb is F433TOY, THIS HAS MORE THAN LIKELY BEEN REMOVED BY THE SCUM BAGS THOUGH.
It has some of my unique modifications, so should be easily spotted as non standard.
Probably a limited market for the parts now, and as it was a runner, it's more than likely being used illegally, on a common somewhere.

PS.One of the balance shaft bearings is worn, so the engine has that distinctive, whine to it.

According to the note from the TRF member: it is all white with a purple frame and red fork gaiters.

So shoudl be fairly easy to spot.
