In reply to estivoautumnal: I'm on my third - 4s cabriolet, and I love them.
First one was 11 years old when I got it, and it never missed a beat in 3 years.
Great build quality and reliability (avoid the 3.4 engines if you can, they can be prone to the oil seals going - repair is expensive, 3.6 is a much more responsive engine too) and of course, nothing else drives or feels like a 911. Very fast, but also as docile as a puppy in town.
Of course most will have been driven in a 'spirited' fashion, and they are not cheap to repair - even if you avoid the dealerships,so make sure you get it thoroughly checked out before you buy, and of course, a FSH is essential.
But get it right, and they are no more hassle than a Nissan Micra, and a whole lot more fun
