I see that there have been a couple of posts about the Lionel MLB trains sets -- one lukewarm, the other enthusiastic. And then there's the 2015 Lionel Cooperstown Collection box cars. As a baseball fan who follows four teams, these items are tempting, but I must draw the line somewhere and just say "no!"
However, for those of you who are enjoying the sets and boxcars or have created a nifty baseball diamond for your layout, here's something I came across that might interest you. The Hamilton Collection has a few baseball team themed 1/43 Chevy Corvette models for sale. It looks like they are resin models though, and available with only some team logos. Here's a link to a page with the Red Sox and Yankees paint jobs, but there are others if you poke around the website a bit:
