Considering what hit it, it is amazing that the quarter glass didn't shatter, or that there wasn't more roof damage. Looks like you are going to need a rear section of a quarter off a 2 door and someone that has experience fabricating fiberglass panels to fix the rear section. When done, and the whole car is painted, no one will be the wiser...
It the car has over 50,000 miles (not kilometers), then change the timing chain and gears as a precaution, if not, you may loose the engine if it lets go while driving. I used to recommend 70,000, but recently I have heard of cars just over 50,000 miles having the timing chains fail. A few hours labor, and about $200 in parts, and you are good to go for a long time.
