Was the contract modified to mention that out-of-state car winners receive the cash equivalent instead?
No, but the contract allows them to substitute prizes if they’re not available, for like prizes of “a comparable retail value” or cash. Again, this is in the AOP - the contestant agreement now is very light on details about prizes (iirc, just stuff about tax obligations and that they don’t owe them until the show airs).
The outdoor TV I got did not match the one I won on the show. It was actually a few hundred dollars more, too.
Comparing both side to side, it appears the biggest change is that they moved paragraphs 11 through 17 out of the contestant agreement and to the AOP. The language still mostly matches the 1992 agreement, with CBS/Goodson being changed throughout.
