That's true Norm. It shouldn't actually matter if it was staying in the UK either. Let's face it, when you take a Stratos rep in for MOT the guys in the station are more interested in the car than the description on their screen.
I think you'd have to encounter a right jobsworth for it to be raised as an issue.
As the cars are also usually insured by specialists then az long as you tell them you are insuring a Stratos replica then it shouldn't be an issue.
One caveat on that though, if you have a big claim and the underwriters get involved, if the car is clearly not described correctlyon the V5, then it might be an issue.
