1:32 is a more commonly used scale, and there might be something available. 1:35 is a common military model scale, but even if bits were available, might look too small.
About the only 1:30 models that I recall are the original Scalextric, but even they went to 1:32.
Nowadays, 3D print shops have the ability to rescale their existing lines without massive retooling costs, but will still not be cheap.
