I test drove a 335i convertible, a 135i convertible and a Z4 s35i before buying the Z4.

The cars' performance was within 90% of each other. In normal driving (not track) they're capable of the same, insane and illegal speeds.

The difference is how they feel around you.

To me, the 335i felt bigger (duh!) and more like a sedan.

The 135i was a blast to drive, but a little too "boy racer" for me.

The Z4 felt as confortable as the 335i, and almost as quick as the 135i but felt a little softer. Of the three it was the most fun to drive as a convertible. It is also the car I felt the most at home in and with the design I liked best. It's all personal.

Drive all three. Then look at the trunk space and the rear seats, and ask yourself if you'd ever need them. If you won't, get the Z4.
