As MiniKid implies, whether it still counts as the original car or not depends on how much it is modified. The rules treat 'radically altered' cars and kit cars in the same way. A lot of people kid themselves that their car is still original despite being very different from the way it came down the line and simply don't bother getting the test done. The drawback to this is that it leaves them open to prosecution in the future if or when somebody official finds out. If there is an accident involoving a radically altered vehicle that is insured as standard then the car and driver wouldn't be covered at all. Unfortunately there are no longer any up to date official on-line sources of information on this since the DVLA's own website was absorbed into the Direct Gov site which is riddled with errors. You should try phoning the DVLA or visiting a local licensing office and getting information from there directly. Or see if there are any kit car forums that may know the information.
