I'm with cudabuyer above, as I have also built a nut and bolt resto-mod Challenger vert. Even with a very *complete* donor car in my case, it is not hard to run up 500-600 hours in a correctly done body and paint restoration. At $50-55/hr for competent resto shops in most major markets you can have well over $50K in getting a shell ready (donor car plus repair/refinish), add for big tickets incl. engine ($24K for my hemi), trans, Dana or 8 3/4 setup, suspension, brakes, interior kit, instrument cluster, dashpad, top (verts) - it is easy to have $100K ++ in an E-body project. It takes a lot of time and money to chase the parts to do one of these right, and compared to years back, we have it easy now with Harms, Frank Badalson/Roger Gibson, Resto Rick, Year One, Totally Auto, R/T Specialties and many other vendors stepping up the E body parts supply. IMO, its worth every penny.
All of the hemi projects I've seen come up on ebay over the last year, with the exception of one (or two), have been ABSOLUTE junk. Coupes without torque boxes added, no hemi snubber plate, 318 radiator/core support, no rallye dash, etc, etc. If they get $50K, $60K, $70K, whatever for these weak sisters, buyer beware. To be able to drive and show one done right is, in mastercard terms,..priceless.
BTW, Top Banana will be back in the 2007 season with some new goodies to show off.
