So my father took his car in to have the head-gasket replaced. Quoted at 1200-1300. Whoever the shop sent the head to for resurfacing did more work (valves or something, not sure) and there was no communication. 2 weeks later and cars done, 2k'ish total now. My fathers not elderly, but he's getting up there. Trying to make sure he's not getting taken advantage of. I take strong issue with the lack of communication and a +50% price increase without any form of approval. I'm running him to pick it up tomorrow. Intend to get him an itemized invoice and really question it (I'm annoyed). Whats the word on itemized invoices in IN, do they have to supply one? google searching only comes up that it is required in MI. I understand stuff gets marked up by the mechanic, but I don't understand a $700 jump without approval/communication.
