woo hoo! 
2005 BMW Z4 Convertible 2.5i 2dr Roadster (2.5L 6cyl 5M)
What's not to love?
 I had the Z3.  This car is a vast improvement.  Hugs the road & corners much better.  Smoother ride.  Many luxury features the Z3 didn't have, such as rear glass window, auto top without anything to hook or unhook, xenon headlights, run-flat tires freeing up trunk space, roomier interior with new retro design, great cup holders!  Better stereo sound than the Z3 too.
