don't see why they would have to take the whole car apart though.
if you don't remove the parts and just mask up the trim. the paint will be pealing off everywhere you mask in a couple of years. i am sure you have seen lots of cars where that has happened.
removing trim and just masking it off is the biggest reason for price difference.
also just masking off the trim it will be mush easier to damage it when you are working on the car.
