Well, the butcher's bill is as follows...
Black RH insert in bumper is cracked. Replaced with one I had in the shed.
RH foglight. Also replaced with one from the shed.
The air filter bottom fixings have sheared off. Still to work out a bodge to fix this. Probably cable ties...
The top wheel arch fixing of the bumper itself is cracked but still attached by a tiny bit. Glued in place, but needs reinforcing somehow, but it will need to be thin.
Power steering pipe. It seems to be OK, but the fixing brackets have sheared off.
So far I have stripped and rebuilt the bumper. The dents came out reasonably well with careful use of a big G clamp.
So, as we stand, both cars are off the road. The Carlsson will be priority tomorrow. Fingers crossed it will be quick. The extra underseal arrived this afternoon.
