horses for courses...one of my friends had one and had no end of trouble with it, whilst my next door neighbour has a Boxster S which he loves more than life itself!
As with everything, do an extended test drive. I once owned a 996 Carrera 2 which I bought after a 10 minute spin up the road, thinking I was fulfilling a boyhood dream. The day to day practicality was far from a dream, my gf hated it, it soon went at a hefty loss. I wish I still had it as a weekend car, but as a sole vehicle it just didn't fit my requirements.
Unfortunately, I found it was a bit like sh@gging your dream girl and finding she wasn't all that between the sheets! Bloody fast though!!
