I bought a Machine
 I was attracted to the Z4 because of the exterior design.  I didn't realize that I was buying not just another pretty car but a machine. I think the car performs best when driving at 90 mph and above.  Handles wonderfully and clean.  It's the best purchase I've made in a long time.
