Worthpoint is, I believe, a clearing house for auction and sales information. They charge you to get pricing info. I wouldn't use it enough to make it worth my while.
I haven't seen any current or past listings on Ebay for the Turkey Hill Car.
A Wawa car! That would be cool! I was listening to the radio recently, and the show host was talking about two politicians from either end of the state. As a joke he said he would like to hear a debate between these two men, and the debate would be over, which is better, Sheetz or Wawa!
If you want a cool custom reefer, get a Lionel Penn Dutch Operating milk car. There are a few "Penn Dutch" cars for sale on Ebay right now. These are cars that I designed, and marketed for the National Toy Train Museum.
