I'm sure we have all seen buses which are obviously newer than their plates suggest - just to get free road tax.
However, not a worry to EB owners, is the fact that pre-1960 cars do not need an MOT.
I have seen quite a few cars which on paper are 1956 Ford Pops & the like & thus do not need an MOT.
In reality there is very little original content at all. e.g. Greatly modified chassis, Jag IRS, Fibreglass hot rod body, V8 engine, sometimes no mudguards at all. No MOT needed.
I'm not against mods or customising vehicles but I think standards need to be maintained for the safety of the general public. Perhaps this is what the concerns are about.
PS my 1959 Frogeye does not need an MOT. According to the insurers - if I tell them it's OK then it's OK. I think this is wrong. I think a few court test cases, post accident, will need to be seen. (Though not mine I hope!).
