i sold my old vectra b o2 2.2 sri for 1300 3 years ag, it was in mint condition with everything replaced or serviced
was a cat C, only had front wing, headlight, suspension arm, grill damage
with Vauxhalls if the front bumper is damaged an OE bumper new is like 500 - 600 quid then you have another 500 quid to prep and spray
car is worth like £2k then you understand why it is so easy to write off
