2004 BMW Z4 Convertible 2.5i 2dr Roadster (2.5L 6cyl 5M)
Great Z4
 Great fun car.  Automatic roof is 
great.  Smooth acceleration, nice 
cruising (though the engine revs a 
little fast on the highway).  I have 
driven it over 500 miles in a day and 
was comfortable (6'1", 230).  I took a 
db meter on my test drive, and with 
the top up it was just a few db higher 
than my Acura RL.
