OK - so I started the work....
Removed the driver side wheel liner for general access to the dented wing, will be getting one of those mobile guys to take a look. Removed the lights, bumper, crash bars (the lower one is almost undamaged but will need replacing), condenser, engine cover. Salvaged all usable clips from the lights & bumper, only the left fog lamp blank survived - turns out I do have both wheel liner covers, but passenger side liner has a possibly fixable broken lug.
Noted some extra damage - top clip for intercooler is broken on the front edge which is probably fixable with some thin metal and araldite. Put some water in the tank and sure enough radiator dripping immediately from passenger side. The bumper clip sections riveted to the wings have broken clips at the front at both sides. Plastic tray under the engine is broken at one side, probably a Copart fork lift.
Special thanks to whatever idiot last did up the engine cover probably with an impact driver as the brass thread part has stripped the plastic it sits in. I really don't want to have to dismantle all that to replace whatever that big plastic part is, so I'll probably use araldite or similar to refit the brass part and be careful doing it up....
Left rail flange is definitely bent and possibly the rail too slightly - does anyone have the exact measurements from side screw holes to right side? I have an idea for taking the bend out of the flange as there's not much room to swing a hammer - get a 1.5" thick block of steel with the bolt pattern drilled in it - and screw it down tight. Right one is in better shape but still has a slight bend at the top, definitely fixable.
Tackled the radiator next - OH MY GOD THOSE ****ING CLIPS, these were easily the worst part of the day along with limited access to get the hoses off once the clips were broken away. Some of the hoses could do with replacing maybe as the clips were done very tightly. Next fought the intercooler for just as long - same story with short inflexible hoses and evil clips - didn't realise intercoolers had oil in them, I don't know anything about turbo cars. Oil everywhere but mostly into the tray still there with antifreeze in it.
Took lots of sandwich bags and rubber bands and put them over all hose ends on exposed hoses and electrical connectors. Ran out of daylight and tidied up by torchlight.

Summary - costs have increased a little which is a shame - little concerned about the passenger frame rail but if it is bent it's only very slightly. Not sure how I used to do this when I was younger and not ache afterwards, but I'm glad the worst part is done - those hoses and clips, and fighting to remove parts from a bent slam panel.
