@David I can model, but what I can't do is python, could you figure out a script that would put the player in the driver seat without causing parenting issues?
@RadishoftheOpera ok, first off I'm making your scene more orignised, so I can fix stuff. then make the jeep always work (with the wheels) then make the player get in the jeep.
all you have to do is see what needs modeling, and then you could even work in a different file. When you are done we move your object in the the "master game blend."
