Sometime in the late 90's I bought a Mk1 Escort based Dutton Sierra kit car which for some reason bears the original number plate of the donor Escort -
1969 H-reg. It's down as a 'Historic Vehicle' on the V5 and as such qualifies for 'free' tax discs. Obviously I'm rather keen to keep the 'free road tax' status but I need advice on how far I can go with modifications before 'they' decide it is no longer a Historic Vehicle. It's been garaged undergoing modification since 1998. It has grown a 'new' modified Suzuki SJ chassis, Suzuki Samurai axles and 4X4 transmission along with a 2.0i Opel Manta engine & box, coil suspension all round and disc brakes front & rear. When finished it will also have a full roll cage. I send in a SORN declaration every year but all the info is for the Dutton in it's 1.3 Escort form. Bearing in mind the desirability of Historic status should I declare the mods all in one go? Or should I add one or two of them to each SORN and hope 'they' don't notice the gradual change. I've got a SORN due for return this month and the vehicle will probably take another year (and another SORN) to complete. Any sensible, practical advice would be welcome.TIA Simon H
