MPC for me is OK. I have a lot of Post War, MPC, Modern and the newest production. The F3's, Trainmasters and GG1's are fairly good runners and the paint schemes are decent. They made a large number of passenger car set to match the F3's. All said I have about 700+ pieces of MPC in my collection and I am happy with it. Plus most of the engines runner pretty good.
Just my 2 cents worth.
