Differing design on wheels front to rear?  It's lost some 911 appeal - to my mind..!!

 

Have to remember this is a mule, so they throw on whatever wheels they have sometimes.  Even the metallic strip around the window does not go all the way around on this example.  It is for testing, not to show the final design.  I doubt either of those wheels designs will be available on the 992.
