dave first of all its rob....aka bender,and C&U reg s are applicable , C&U regs are infinitely boring and definitive,more so than sva they would be the ones current at the time of manufacture.I only know this cos along with a mate we manufactured beachbuggies (in fact he still does) so i sat down and went thru it all many years ago and believe me that is one thing i would not want to go thru again.
I only mentioned plod as you will get some techo jobsworth point it out if they pull you over merely so they can give you a ticket ( cos its the only page he read).
