I would say the Z4 strikes a perfect balance between sporty and classy. I drive Ford's and Chevy's, and I would imagine, I would only be envious of the handling characteristics of your car.
The Z3 was the precursor to your car I believe, similar styling. Did you have any opportunity to compare the 2 vehicles?
Great looking car Trajan...Though I'm sure the resident troll, will simply call it a mid life crisis vehicle, like my Corvette is.
Have you had the opportunity to give it a good flogging on some twisty roads? Bet that baby really shines there.
