I do not think it is a good idea. Having lived in Europe most of my life, it is my experience that the motortrade still has a bad name, even with all the government control.
In European countries the additional cost is quite high, but remember most of these countries do not have business rates!
However, most 1, 2 and 3 man band independent garages have disappeared as the vehicle manufacturers have taken control.
I would think very carefully about giving more control of our lives voluntarily. In my opinion Big Brother is watching us to much already. In fact, government control in Britain and the rest of Europe seems worse now then Spain when Franco was ruler!
