Thanks, I've decided to repair it as the frame rails look straight and it starts and drives.

At a minimum It will need...

2 headlights,
bonnet,
radiator,
fog lights,
passenger side quarter panel,
new tyre,
some suspension components,
bumper,
bumper internals such as the cross member,
dashboard,
dashboard airbag,
steering wheel airbag,
windscreen,
grill

from my initial searches it looks like sourcing the SRT6 bumper will be the most difficult to source, I may have to put a standard bumper on there and replace when one becomes available.

It's going to be an interesting journey! will upload some pics soon.
