I guessed that it would be difficult ot retro fit the fold down rear seat/hatch.....not to mention expensive to find the parts! Looking at a 71 base Mach 1 in NC, looks like the drivers side frame rail is gone, along w/much of the floor on the drivers side, some rust thru under the rear seat, trunk and passenger front floor too. Deck lid is pretty rusty along w/bottom of passenger door. And the car has been fixed/repainted what looks like maybe 2-4 yrs ago, so I know lots was filled then. The front crossmember that has the struts mount to is rusted badly on one front side- and that appears to be a $300 part. Even though the car is pretty complete and has a title, Im not going to buy it for $5500 since the condition of the motor and trans is also unknown...... comments???
