Seems straight forward enough to me. As you say Jon, it's either illegal or it isn't.

Some time back there was an Indy for sale (had West tobacco livery) that was registered as an Austin seven! Not hard to work it out. It would stand the same test as a ringed car me thinks.

I had an email recently and here it is......

I've just bought an MK Indy privately and have discovered that it is called a Dutton on the Registration Document and tax disc..? Is this normal or am I likely to have a problem. The car has covered only 160 odd miles since it's SVA test apparently..?

Oh dear!
