about 5k for an in and out paint. its a massive job. i'd maybe consider just repainting the outside only as a white pearl. it'd look nice and cost less 'cos you could leave the engine bay, door jambs and inner tray the way they are. my figure is a rough est for what i would charge. not taking exterior damage into account, take it to a few shops get some quotes and get the one that is in the middle.
