Take in a few car shows, cruise-ins and the like. Take your grandfather with you. You will see what is out there and talk to the people in the hobby. They can tell you face to face what to look for, what to avoid, and will encourage you in your endeavor. You will be able to compare cars "in the flesh" and have a better idea of what to expect. Car people always like to talk cars, and you will most likely see a few for sale signs to whet your appetite. Good hunting, Rick
