2 Part or Not 2 Part a '72 Valiant
I say try to sell it first but be prepared to nearly give it away.
Once you work through the "If only I was closer" and "If only it was a 2dr" crowds you'll be lucky to get $200 for it.
Not to be cynical but I've been there several times. People think 4 doors are amusing or sorta cool as long as they aren't the one having to buy one.
Good luck..try to save it.
