pc > console in this case.
You can add a retarded amount of cars, and bikes in the pc version by modding it. Along with planes, clothing, weapons...everything.
Just a few cars and bikes:
GSXR1000

Tumbler bat-mobile

Turbo busa, i would put it up on the rear wheel and do circles around the interstate no problem.

Pretty cool truck, it had front and rear steering.
Weapon mod:
Tattoo mod:
Just a few of the hundreds of mods that are out there.
EDIT: I could see them and some others could but i went ahead and hosted them my self. they should work now.
