Solid and Complete...at that asking price, it's a no brainer. Even if so much of it needs rebuilt or repaired, hey... at least it's there! I bought my '68 Coronet in the same condition, except the 318/904 was still there, and the interior was shredded. All those little bits and pieces you would otherwise need to find, add up to BIG money in the end.
I've seen gutted, roller Road Runners for $10K - no way, Jose'! That Plymouth may never fetch $80K at Mecum, but who cares. Build it the way you want it, and drive it with a big sh*t-eating grin on your face!
