It must be hard to pick a favorite as there are a couple of hundred different ones to choose. There are leather, plastic, metal and novelty fobs from all over the United States and even Argentina and Israel. Some are made to hold your rolled up drivers license in a tube and some will hold change for a parking meter. What ever you collect they make an interesting display at local and National Meets. Many also have a dealers name and address embossed on them and it would be fun to find a dealers fob from where your car was first sold or a dealer near your home! They are not easy to find.
