Hi, I am new to landyzone. I own a 1999 defender td5 and am contemplating getting a series 2 as a project vehicle to work on in my spare time. I was going to do a 3.5l v8 conversion if I ever own one but am slightly phased as to the legal side of things. I know there is a points based system for keeping the classic car status, mot and tax exemption. But no major changes are allowed including changing the engine to a nonstandard engine unless it was an alternative original equipment engine. Has anyone who has done this had problems keeping mot and tax exemption or is loosing them just part of the conversion?
