These, like all of the Marx cars, are a bit out of scale. not as bad as some, But can be a bit large. I think that with the correct wheels and tires. I can make these work. Of course all modern running gear as well. should be fun to try anyway!
Yes Dave, I am. After a little research, these cars are way closer to scale than the other Marx offerings. I think they will be fine. Especially done up in series.
