The Runnings flyer in Fridays news paper had 1/32 scale trucks on sale for $9.99.

1:32 tends to be a bit small, unless you are actually modeling in 1:32.

I agree they may be a bit small if you are not modeling 1:32 but if the detail is right you can still use them for modeling? Besides Lionel does and they are still selling well even with their light speed.
