In 2016 I spent $13k on an exterior paint. Minor rust repair. Resprayed the original Color. I did the glass and chrome removal, they welded the holes left from the side molding removal, and after market mirror holes. They tested old paint depth and checked any questionable areas. Shop is Euroteckbodyworks.com a noted Porsche shop. I replaced the glass, bumpers, mirror and badges.
A full strip and repair here would run $30 - 50K based on the amount of rust repair. A mechanic shop on the east side of the Seattle metro area is $130 -160 hr shop time.
I am aware of at least four stock and custom restorations in the area of $125k, $135, $160 and $??? a Gold winner at ZCON.
