hmm, i wouldnt buy it back off insurance mate to be honest, not for that kind of money, yeah a grand but not £2200, from the out side the damage dosnt look overally bad, but at a glance and with out inspecting it any further id say shes fookin bent big style, for any dash to split like that the bulk head has taken a right clout. You choice not mine, but if you bought it for the money youve said i doubt youd get it back even if you sold the engine/etc for £1200 youd not make enought back to clear what youd paid....
bummer about the crash, hope you werent hurt like!!
