The reskin price you were quoted is fair IF they had to remove and reinstall all items, seats , dash etc...
I'd advise that you add your car details in your profile as you will get more responses when folks don't have to search your earlier posts to see what kind of car you own.
Back to the seats... The Aurora has a bit different seat design depending on the options ordered it appears (some have headrests, some look to be Jaguar, etc...). This site will may be helpful.
