2003 BMW Z4 Convertible 3.0i 2dr Roadster (3.0L 6cyl 6M)
Now if only there were an M version...
 This car is a pleasure to drive, even around town.  I have the Steptronic automatic version as my wife doesn't drive a manual transmission.  Overall gas mileage is about 24 mpg with a couple of long, mostly interstate driving, trips coming in over 30 mpg.  We have taken this car down the Blue Ridge parkway from end to end and around Cape Breton Island, top down.  Pure pleasure!
