Could probably write an essay on this but at a basic level, my view is that us MV owners do it more for the fun and because we like quirky vehicles. It can be good to perhaps put some kit on which 'goes' with the vehicle, but down to every last detail? I suppose that depends on what you're trying to achieve.
At the end of the day, for us, the vehicles are the things we should 'dress up'. So long as we keep this old metal preserved and on the move, as they are important pieces of history, that's all that matters? We get the same level of enjoyment out of them regardless of what we're wearing or what our main interest is.
Our vehicles go out during the show season, and occasionally get a drive during the winter. It's all about driving, enjoying and showing them to joe public. It's worth it for the stares and smiles you get from little kids!
Don't know if that contributes much!
