A Motor vehicle, which I suppose includes a motorbike, that was FIRST USED, which is the key, before 1960. The first used means if you got a collection of old bits and built a copy, though each bit was pre 1960, if you can't prove it had been 'used' on the road somewhere before 1960, it would need MOT and road tax etc. Going to be a whole world of fun and games considering the majority of vehicle of that age would have had major repairs re builds, renovations. Like Grandad's broom, three new handles and two new heads.
