Because of the strong resonance with my name (there is strong evidence in psychology research that we tend to like things that are similar to our names - a term called implicit egotism), I briefly entertained the idea of getting the Z3.
But being 6 feet 2 and 200 lbs, it wasn't easy to fit in it...
And then Z4 came out, and the car no longer resonates with me, so I just gave up=)
