sell it on the bay,
I got 700 for an astra with a blown engine that was far from mint and had way over book miles - MINT low milage book value was 1200
got 500 for a 900 book value car I crashed (someone brought it for the seats)
and got 250 more for a would be insurance write off than the insurance were offering... (something like £1800)
just make sure you list ever scratch, dent and ding.... every mark and tear on the interior and clean it before its collected..
(sold other cars as well never had an issue)
