when i had a little bump in mine last year, i didnt claim for mine just the other car, as i knew they might write it off, if it's minimum damage to the other car cant you pay for that with cash to be repaired, or is the other driver one of these "got to go through the insurance mate"

as for yours, you can get all the parts second hand, you might be able to bend the door back into place, with a little filler and paint will be good as new, second hand steering column and a set of locks and matching keys, job done
