sorry to hear that ,were i live people park to close as well ,
your looking around £200 per panel at any decent body shop "i live in north east , co durham area"
i had my car vandalisied last year and when i took it to body shop i asked them how there priceing works ,he said its not just the size of the dent or scratch its the labour time involved in masking up , sanding etc.
hope this helps
