Had a 987 S a couple of years back - fantastic car no doubt about it (mine did have bose, dont worry your not missing much!).
Looking back now, the only thing that let it down was the sound, it was just a little too reserved for my taste, bearing in mind I like the standard zed exhaust im not a big noise junky. Add an aftermarket exhaust or porsche sports exhaust and it would be spot on.
At the time (2006), I paid near enough double for the 987 for what I paid for my 07 zed last year - at those prices zed wins all day long. Now the 987 prices are down though, much more difficult decision..
