Racing cars which have been converted for road use never really work. It's like making a hard core adult film, and then editing it so that it can be shown in British hotels. You'd just end up with a sort of half hour close up of some bloke's sweaty face.
I'd just find a story in Canada and come and do it. Combine harvester banger - actually I've done that: banger racing up in Red Deer [in Alberta, for his 1998 doc series Extreme Machines].
