Chips Away* http://chipsaway.co.uk/ did the repair for £125. If none of the panels are cracked, get Chips Away* to visit and give you a quote (these are free) before thinking of new panels. You can't tell that mine has been on it's side now (the £125 also included a scrape on the other side when I scuffed a wall parking it at work...).

*Other franchises are available.
