Love the Z4
 Just purchased my 2015 Z4 s35i Alpine White with the Coral  Red leather interior.  The car was Certified with only 2,348 miles.  I owned a 2004 Z4 in 2008 and really liked the ride.  I sold the Z4 and purchased a 2006 Corvette convertible.  It was a nice car with a lot of power but was lacking in the ride.  I was looking for either a Z4 or Mercedes SLK.  I found this Z4 that was exec driven and was totally loaded with all the bells and whistles.  It rides like a dream.  All of the controls are right at your fingertips and the seats are adjustable to wrap around you.  The wind defector makes for a quiet ride with the top down buffering the wind making it easy to carry on a conversation or listen to music.  All-in-all the Bimmer is the ultimate driving machine.
