I have the opportunity to purchase a 1987 Hammer. I understand there were only 13 made for the U.S. market. This is one that was made for the U.S. market. It is not grey market. I can not find any onformation regarding how much the car is worth. The car listed for 160+. It has 58,000 miles in mint condition. He is asking $35000 for the car. Any input or help would be greatly appreciated.
