IMMAJ 
2005 BMW Z4 Convertible 3.0i 2dr Roadster (3.0L 6cyl 6M)
Best Value
 This car has the quickest top retraction in the industry: 7 seconds! It handles well, comfortable (except when the top is up and you get out of the car. But overall, a great value and a sexy ride. The only design change I would do is revise the back of the car like the Z8.
