you need a friendly DVLA inspector or a woman one who doesnt know what shes doing and some shell reciepts that bend the truth slightly.

i think theyve closed all the loopholes for old cars claiming the work was done like 10 years ago You used to be able to use the loopholes to get retrospective based on the old laws for pre-sva aged vehicles by saying you didnt realise what had been done etc. Loads of old cobra replicas running on jag ID's got round SVA in that way by showing it was built before SVA rules and getting retrospective approval and new id. I suspect theyve got rid of all the loopholes to get round it now though.
