Right, Ihave decided to keep the miggy for now and to repair it. I may change it soon depending on a few factors. So time to get the parts in 
You know it makes sense 
Indeed it does...
Tailgate, bumper and potentially the rear crash bar here (I think I have an unmangled one
) ...
That's great, thanks 
However, Ihave a conundrum. Parts need painting prior to fitting, parts are near Crawley. I cannot fit parts until I remove boot lid and inspect the damage on the boot floor by the bottom of the boot lid. Once I remove boot lid, boot will no longer close.
So, how can I be sure that the boot floor is ok without removing the boot lid. Can I tie it closed again? If so I will kick the firker out 
What about opening the boot lid, ripping the carpet trim off the inside of it, attaching a ratchet strap to the metal work somehow then looping it around the spare wheel (as long as the retainer is still holding the spare in).
To move my 2.6 with rear end damage I had the same issue, I just used a bungee cord and some strong tape to hold the lid down although I appreciate a saloon is different!
