What's it worth? 1972 Plymouth Scamp

MY wife. Couple years we gave $1500 for a complete pretty darn solid, straight 71 Duster,plus a sb. It was filthy in and out, had a few weeds growing thru the floor. Stopped at the car wash on way home and hosed it out, inside and out. Then she says, is this the same car?
Few weeks later, tires, radiator, bakes, we are driving down the road. She says is this the same car?!
The next year I have done all the body work/painted it, she asks the same darn question. I replied "I gave a dude $6000 for the paint work". She replies, " YOU ARE DEAD!" lol.. true story.
