for awhile I was part of a group making a westfield clubman. for some reason they are exempt from crash testing (I think because the general desgn has been tested before) however if they have all the stuff a car needs FUnny thing is they need window wipers even though they dont have a roof) they are perfectly road regoable. brilliant little cars too, 600kg+20v silvertop..
oh and you need to get tyre placards, a plate that says your not allowed to carry young kids ect. find an engineer and have a gander.
better yet get onto the Westfield club and ask them.
