Yes Strummer my friend I know they are four different things. My question was whether there was a general rule about the fourth item, the trucks. (By the way, I just ordered my second Gibson ES 335, the Memphis model. :-) )
Thanks for the advice from everyone. The product is only about a $35 Lionel car, and in the pictures, the trucks look plastic, but I was hoping that when the other three items are metal, the trucks are automatically metal too.
Folks who list several NIB cars on Ebay are often more ignorant than I about O gauge (yes, I know its hard to believe), and retailers who lists lots of cars don't want to take a unit out of the box to answer an isolated question about one car.
There is no mention of die cast, so I guess I'll live with plastic. :-)
Thanks again,
Mannyrock
