What drop-top would you consider as a replacement to the Boxster?

The mall I work in has a BMW dealership in it so I see all the new cars everyday. They have a 6 series and a z4 coupe thats new in there. They also had a Z4M in last month. By the looks of it, the coupe looks quite nice, I didnt think Id like it due to the older style coupes (ugly), but its pretty clean. Now a Z4M coupe... thatd be a hard car to not want to buy. Personally Id buy a hyundai tiburon and put a V8 in it, with nos, and lots of stickers on the side, with air ride suspension, and a sweet body kit. And still have 20,000 left over.
