At least $60,000 and perhaps two years worth of restoration efforts.
Govdeals has an auction going on right now for a true classic piece of Americana incarnate. Right now the high bid for this 1940 Plymouth Roadking is at $3820. But since the auction still has well over five days left, you may find that this Roadking will likely hit the five-digit mark before falling under the hammer.
This is what a fully restored one look like. A rolling master piece. Wanna get started on your own? Feel free to bid it up or better yet, just live vicariously and let others do that costly deed.
