For ultra modern you're generally supposed to use 1/43 scale cars, and 1/48 for vans and trucks and bigger vehicles. At least that's the sizes the ultra modern community has agree on as being most accurate. The thing about "scale" is that there is no regulatory body ensuring consistency, so take the scale measurements with a grain of salt.

Pic related is a 1/43 car, the UPS truck I posted above is 1/48
