I'm actually going there on Monday (Bedford branch) to get my van done, so will let you know! They did say that they will be using the more expensive vinyl after considering for a moment whether the standard one could be used or not.
Hope they're not talking poop, but they did seem to know their onions. And being a franchise they must answer to someone if it goes pear shape, so I'msure they wont want to risk their licence?
