Hi and welcome to the OMG! i crashed my Laggy2 club
yes that is very fixable, and for a lot less than the insurer will get charged for.
contact these guys
they might still have the graphite grey lag in stock.
for the bumper, wing and door, steering rack, lower arm & complete OSF Strutt they are always worth a call, as they can courier, only wish i'd done it when i'd smacked mine up.
its probably much the same as my accident, but with wing, door and bumper included. its sods law you'll need to get the alignment of the OSF inner wing checked.
what are the GAPS round all the doors like???? from that pic, even i can see the drivers door is buckled on the top edge with the roof, the question is, is it just the door thats twisted or the cabin safety cage???
did you have any seat belt pretensioners/airbags go off?
As salvage you'd be lucky to get £700 scrap for it!
for insurance its probably worth £3000-4000 as a write off, before excesses kick in.
for about £500-750 cash you could have that back on the road (not including alloy wheel)... though you may have to spend about £200 on alignment checks and corrections once the busted bits are replaced.
