Dear Knarf,
I'm not too familiar with your regional prices, but that seems rather exuberent, especially if it is in American dollars......I feel a serious dose of shopping around is in order. I do know that replacement panels and floors are available from K&K Manufacturing - note especially the 'patches' (I think there may be one for the rocker panel) - it might help to cut costs if you got the panels yourself rather than through the body shop who is doing the work. One has to start somewhere, I suppose. The bankers love me since I got my 107.
Good luck,
Daniel.
