 Great roadster with just about the perfect balance between performance and comfort. People often complain the weight of the hard top and it's not as engaging as the Porsche Boxster/Cayman; but hey, the Boxster is a few grand more expensive even with the base form and the s can easily be $20k+ more pricey. If you don't track, the z4 with the N54 engine will be more than enough performance for your daily use. Also, the hard top gives you a sense of security versus any of the soft cloth top, plus looks way better when top is up. Since the new z4 will come only with a soft top, I will just keep mine until the wheels fall off. There's really not many choices if you want a modern hard top roadster (all come to my mind are z4, slk/slc, sl, Ferrari California, mx-5). I think the z4 has a sweet spot in the segment in terms of comfort, performance, style, price and will hold its value pretty good in the future.
