Might be trading my Wagon for a Dart Charger..

Hey guys, I just wanted to ask your honest opinions about what I should do. I've been working on this 66 Dart wagon for probably a year or so now, and just got done putting a brand new built 318 with 360 heads and tons of money spent in the right places.. I spotted this Dart Charger factory 273/4 speed car a few months back and just can't stop thinking about it. I assumed it sold long ago, but I gave the guy that has it a call today and he still has it.. And he's interested in trading for the wagon. The Dart Charger does not run, but its so complete and clean that I really think it wouldnt take much to get it going again. I really want a 4 speed car. But if I wanted to get another 66 dart wagon, I would be screwed. What do you guys think?
