I found three RRs within 50 miles of my house last year for under $1500. all projects, but all solid. A 70 (B5/383), a 72 (340), and a 73 (E5/340). Also a factory 4 speed Duster, and a T top Aspen R/T and a Super Coupe- both with perfect quarters and nice interiors.
There were so many floating around, I decided to buy a 22 car garage, so I could start buying cars. That deal came together in Feb, and I've only found 2 parts cars with bad quarters since then, besides my Sat. At least the "warehouse" is cash positive and I still have five personal units there. I watched two of those Roadrunners sell on ebay for tripple the craigslist asking price after being on CL for 8+ months
