Apologies for the bump from 2020, but had a related question that didn't feel like it justified a new thread.
I just got to the point of logging the Rafferty CS retirement in question, and the retirement happens at a weird time. 3 complete games, 2 cars, and a total of $63,105. He plays his third game (crossing $60K) after having already crossed $50K and having already won two cars. Winning the car retired you early on (when the show was giving away $30K+ cars), and from the original post, later on winning 2 seemed to do it. But not here.
Did the show self-impose a $60,000 winnings limit at this point? Every mention I've seen of a network/O&O cap at this point was for either $75K or none - and what was the network of record for this version? It filmed at CBS, but was airing on [edit: Multiple O&O's - NBC in LA but ABC in NYC.] Bill mentions the contestant has hit the winnings limit, but never says why - and gets in a full game after his second car win.
