Finally got the confirmation from an assessor on Friday that the insurance HAD to send (as i dont think they believed the quotes)
and that it IS beyond economical repair....
Total Loss contacted me this pm (Monday) with offer
Guaranteed £13k as agreed in Jan, but of course they have all jumped up since then so Im well short....

Comparables are £15k upwards (most are £18k +)
The real kicker is.....salvage has been put at £6400!!!
So they made decision for me, the vettes going.....and ill need to draw a line under this and move on....
Moral of this is
1) DO NOT CRASH (obviously) unless its a little one

2) Allow a bigger contingency percentage on your estimated final value, than you think it might be worth!
It appears its only a few £'s extra for each £1000 added.
3) Salvage has also gone up (others I have spoke to, said it used to be around 20%) Mine came in at 50%.....
So DO NOT expect your pride and joy at a price you can make good and run about with again!
Hope this helps someone...
Drive safe and enjoy them for as long as you can guys!
Cheers
