Would this be a deal breaker?

Hey guys,

I finally found an actual Demon that is selling for $5500 with its numbers matching 340 and 4 speed. (It currently has a 318 in it). Surprisingly the only MAJOR rust is on the bottom of one door. And on the quarter.

Basically, I know how to replace a quarter, but is this also effecting other areas? And will it be not so complex to fix?

But, most of all, would this make it not a good deal?

If you know how to do the bodywork, and weld in the repair pieces it needs then its a good deal, if you have to pay somebody else to do it , not so much. Id take a chance on it, because i can repair all that stuff myself.
