All cars use only one material and one texture.

You can set the texture size to the lowest possible quality and the final quality of the models will not change.

Also, all the machines have their wheels separated and the pivot of each wheel is located in the center of that wheel, so you can put each wheel in its place to use these machines and adjust the rig of these machines.

The wheels are named as follows:

Right front wheel: wfr

Left front wheel: wfl

Right rear wheel: wrr

Left rear wheel: wrl

All these wheels are part of the main car.
