Wonder if that might have retrospective implications for existing modified historic vehicles?
Possibly though going to be hard work for them if they declare everything already built within existing rules illegal ! I'd think the simplest way would be for an amnesty where everyone had to declare their mods to be considered 'exempt' and anything registered from then on would havet o be standard.
That would be the simplest ad most straightforward way so who knows what DVLA will come up with!! LOL
Bigger implications will be for the hotrod resale market with most going abroad due to a loophole which this legislation would see closed.
