I think the Lomax might be one of the kits that is recognised as a kit in France ...I think the 7 type kits are easier to register too ..again , recognised , as in Caterham etc. When we first started the S*mmio's it was a problem. The conversion wasn't recognised . One of my first French buyers was taking the cars into Belgium and doing them there , as it was a lot easier .
The German examples , I believe , are being left registered as Triumph Heralds , I don't think that buyer wants anything that says S*mmio on them ...this can cause issues later on , re-sale etc...I believe ..
It is a minefield ...The problem now is most of the V5c's will say BMW then the model Tribute Kali / 250 whatever ...when they try to access that BMW model on their databases , it won't acknowledge it as a valid BMW model ...
