Impossible to say since only looking at it in the flesh will show up what's broken, and what's fixable. Phone a couple of local body repairers, one of them might/should be happy to come out, and look at it with a view to giving you an estimate.
Sill, wing, door, piller, jigging, wheel tyre, suspension, side repeater and paintwork on a £800 car, yup time for the crusher, even on the cheap 2 or three time the value of the car I reckon.
