Nevin,

The right color can add 100% additional value to the same car in red and Rubystone is one of those colors. I really would have to see the car to some degree. You can send me pics at Jeffery.coe@snet.net or my cell at 203-767-7749. Typically a nice sorted red 968 coupe can bring $15-20k. So again, add that color and you are looking at $30-40k.

That said, originality, maintenance, documentation, additional options, all effect the value.

Jeff
