My past rule of thumb was to not go north of $2800 for a so called complete kit , at a minimun, the body, doors, deck lid and hood, with entire windshield package all in VG condition. Today these same parts maybe $5,000. So many of the basic CMC FF items items need to be upgraded from the basic kit, with the ever rising cost for interiors, tops, wheels and tires , gauge set and all electrical items. Then sublet the body and paint work. Even if you build it as a keeper one has to be a bit of a tight wad. Tally up the cost of a complete chassis engine trans and suspension. Just today I passed up a super deal on a used custom fiberglass dune buggy body and full roll cage , that a year of so ago I would have grabbed it, building a car is a hell of lot of work and those 10 to 12 week build times are now behind me, it's just not fun anymore.
