Please read this and give me your opinion

Hey Guy...and Gals, I have been visiting this forum for years but only recently joined. I am one of the few guy here that have owned their car longer than they can remember. Like a lot of people, my priorities have changed for various reasons and my Dart (among other things) has been left to sit because I basically lost interest. Taking a serious and honest look at the car today, and knowing my financial situation, I think I need to make a move with this car. Now, here is my dilema...if I sell the car I might get 3 to 4 thousand for it. However, if I part it out I could probably get double that.

The car is an all original, matching numbers 340, 4 speed, sure-grip 1970 Swinger. M/S, M/DB, bench seat, perfect dash bezel with NOS tach, rallye wheels. Plus, I have new bumpers, fuel tank and line, and other parts that were never installed. Please...what do I do ?
