Pa3de8,
The Mercury Bobcat was one of the cars that is supposed to be in the second set!!! If you got one, that means they're OUT!!!!!! There should be about four different cars in that set, just like the first run. Can't remember what the 3 other cars should be, but I THINK a mid to late 70's Mustang 2 was one of them!!!! I'll be checking my local Wal-Mart daily now!!!!
As far as I know, reading what I saw in the March issue of the Model Railroad News, by the time that issue came out the Tempo and the Bobcat were to be added to what's already out. Nothing about any other cars.
