Really???

70 dash, 72 side markers, 70? Grill....something isn't right with this car, cracked dash, top of rear seat covered (probably split open from sun), looks to me like bubbles under the vinyl roof, painted engine bay hiding what? He us on crack. If it really were a survivor perhaps $10000 but looks to me more like $3500 to $4500. I am guessing it is a re bodied car with a 70 VIN.

Yep, that thing is a MESS.

Just a guess, the roof is likely rotted seeing the vinyl all frayed up. C pillars are REALLY bad for rot on those cars as well.

The pass side inner fender would tell you what year the body really is unless it got swapped out. Along with the yoke or trunk lip numbers.
