I thought the bike engined car was a design exercise and that it was never commissioned.
As for "almost all" being revealed - fingers crossed that ALL is not revealed as that might be a frightening sight!
It is going to be a busy week-end in March - on the Friday (23rd) I'm at Stoneleigh, on the Saturday it's Loton and then on Sunday a trip over the Pennines to Harewood!
Should keep me out of mischief!
