not cool...unless its a mkI you gotta thinks its gonna be a good idea to get a new chassis (rest is prob wrotten)....you can have the spare shell i have if you want.
That first pic will be quite tricky to repair but the rest should be fairly easy, Hadrian do replacement panels for the front and top edge of the inner wings! If the front is that bad though I'd recommend checking the rear arches too! [:^(]
That shell looks like its sadly a casualty... hate that when another one goes down... MOT will stick a screw driver through that and go 'mmmm fail'. Thats the worst rust I ever seen on a mk1... was it neglected or lay up for a long time???
