What do you think this is worth?

I wouldnt sale it,unless its necesary to feed your famil or keep a roof over your head,not right now any way.With the economy so bad,your car,as nice as it is,wont bring much,nobodys are bringing big bucks right now.With a little more work on your car,it would go from nice to awsome,and people are gonna try to rape you for it right now.There gonna pull the motor out,paint it and the engine compartment,fix the front fender and put a demon tail panel on it,and maybe get 10k for it,when they only give you @$3000.00 for it.Thats what i seen a few similar to yours go for lately.From looking at your car,i can tell you or somebody has put a lot of hard work into the car,im afraid you will be disappointed at what it will bring right now.Id hold onto it a couple more years,and see how the economy goes first

I believe the previous assessment is absolutely correct,on the money($3K).

While your car looks decent, there are issues apparent in the photos, regarding some dents, interior, roof, etc. and the car is a 1974 318 Duster with a Demon front end.

You have put in some hard work, $$$ thus you should hold the car.

The largest Mopar show in the East just concluded, All Chrysler Nationals @ Carlisle, and if you do some homework, you will learn that not much sold.
Even super clean, original #matching 340 cars did not sell at great prices.

The economy=POOR shape right now, real estate, money and financials are very tight. Cash for toys is in short supply.

Unless you are in a situation where you must sell the car, keep it.
