Sorry to hear about your car Bigfoot.
I know how it feels to have your car stolen by thieves. Unfortunately it depends on the car and how the mechanic assess the damage.
All your wiring has to be corrected and the likes of steering column (if not broken, count yourself lucky) etc have to be checked for stress and road worthiness. Then the cosmetic damage such as plastics, seals and the door. If your door is bent back, there will be chipped paint from along the top of your door and/or your roof. Be sure to have this corrected properly as if there is visual evidence of a break-in then your car may be targeted again. If the crease in the door is very weak then best to replace and get spray job done.
Most importantly though, try to get a mechanic that might be able to source second hand spares for your plastics etc. Make sure he dosnt pull your pants down over price too.
Fookers caused me €2500 damage before so lets hope it aint that bad.
