Paul in San Diego 
2005 BMW Z4 Convertible 2.5i 2dr Roadster (2.5L 6cyl 5M)
Highly recommend!
 We purchased this car new in 05 and it has been outstanding. Not a single thing has gone wrong in 40k miles, it gets 32+ mpg on the freeway and combined mileage is 25-26 -- all much higher than estimated! The free services have been great too.
