Cool Baja bug, not sure what it's worth. Talking with a buddy about this very thing the other day. Not many people looking for a complete vintage race car that has been restored. Most people want a project that needs a lot of work. If this Baja has been in storage since the 80's I'm guessing it needs a complete restoration from the frame (or pan) up. New everything. With that being said you are looking at between $18-$25k depending on how much of the work you can do yourself and how good the remaining parts are on the Baja. If you spend $25k on a restoration on this car, in this market right now you'd be lucky to get $15k for it when its completed. With that being said someone is not going to pay a lot of money for a project car that is going to cost a lot to restore. Well, that is unless that idiots name is Rory but their is only one of them thank gawd.
Old race cars are very cool, unfortunately for us there is not a high demand for them. I've said it before, we are in the early stages of vintage off road racing vehicles. We are going to make some people extremely rich within the next 30-50 years but it wont be us!
