"new" 1969 Barracuda

There is a buyer for everything. Some look for untouched / all original. Others look for
" Rotisserie restored to showroom condition".
or " Upgrades include later model large bolt pattern diasc brakes and 8.25 rear ". Then another buyer gets off on aftermarket brand names like Edelbrock, Summit, Flowtech, etc.. the more the better for those .
Bottom line Make what you want of it. If you ever need to sell it, you can.
Having fun with it is the only goal.
