So you cant use a yellow van in case SM get on your back,since when did they or any one else trade mark a colour,
If they contacted me and said anything like what you mention, first off I'd tell them ferk off, then.. please, please try and stop me using the colour yellow, through the courts if you like......

Apart from that it is over-priced by about a third but as they have retired I suppose they can wait, although not too long as it will depreciate further.
