Driver side of my 147 is getting into a bit of a state, few dings, a longish scratch and now the sill looks like it's rotting from the inside out. Want to put it right or sell it before I get to the next cambelt\wishbones\currency extraction service next year. I'm in Stewarton so can get to just about anywhere in Ayrshire or the Glasgow area easy enough. Anyone had to replace the sill already and know what sort of bill I should be expecting?
