Jim, I agree with the others. If you have a reasonably complete engine, gearbox, suspension and a few other parts, the three wheeler is worth what you feel is right. If you plan a first class rebuild, it will probably end up costing more in time and money than you will ever get out of it when it comes time to sell. I totally rebuilt one and had a great time! It more about having fun and enjoying the car. There are not many old three wheelers around, so for me I would buy it if felt right. Plenty of parts and help available to fix/make almost anything. Pay what you think is your limit and enjoy having a rare beauty. If you do go to buy, bring a friend who knows something about what you are looking at.
