Collectable? Not sure. I have 3 of the 125 cars that KLINE made for our AOL online York BBQ's. T@hat was Maury's and Bob Grubba's donation to the 8th semi-annual event which you used to have at York. Allan Miller can attest to our BBQ's.
One went on ebay years ago for $90 but that was years ago. I tried selling one at a few shows for $50, maybe here on OGR with NO interest.
Collectable? I would not lose sleep over it nor even waste my time at York waiting on a line to buy one of the 50. Lionel has a good idea selling this unique car but that is where it ends.
But yes, I agree with someone here that it will be on someone's table for 10x the price or on the fleebay.
