73 Gold duster is it worth anything?

Not worth a ton, the Gold Duster option itself isn't that rare. The snakeskin top option is a little rare, but it's not going to significantly impact the value of the car. They're a cool vinyl top, but vinyl tops are a disaster for cars that aren't garaged 100% of the time or are driven in any kind of weather. Ever.

The car is probably worth $2- $3.5k it sits, depending on the condition of things and what's been done to it. Looks like a good car to start with!

No harm in going with the blue and white treatment, given that it's a '73 and not a 340 car there isn't a ton of additional value in being restored to bone stock original.
