Sold at $6,100, congrats! For what is there, I'd say that was well-bought.
Figure $650 to buy the dashpad (install yourself), another $600 for the headliner (+500 or so, maybe) and a good detail job will make this the queen of the ball!
The Imperial is still available. The deadbeat who won the auction has disappeared. I have listed the car again. I will listen to any serious offers and end the auction if sold earlier.
