So, what's my Dart worth?

Remember, you did say any input is appreciated. Having said that, the car would be more desirable to me without all the drag race stuff. Lose the 5.9 magnum, the built 904, and the 4.11 gears and replace them with something more driver friendly and it will sell quicker. As it sits now the car has limited appeal and you would have to find a buyer with the same taste that you have. A car that nice with a stock power train would sell quicker and bring almost as much money. Then all you would have to do is find someone to take the 5.9 drive train off your hands. To be blunt, I look at your Dart and see another wannabe drag racer 360 belly button instead of a nice home for the 426 Max Wedge that is taking up space in the garage.
