If it were me I'd would take a car this summer. But that's because I plan to get a 997 Turbo cab. I think it depends on how long you plan to hold the 997 S. If you're like me and switch cars often maybe you already have your eye on the 997TT. If so I would get into an S asap and put the money you would have spent on the power kit towards the Turbo. If you're not like me and plan to hold the S for a number of years not wanting a Turbo etc. then maybe you ougta wait and get the power kit. I wouldn't spend that kind of money for a power kit when you could have a Turbo in the near future.
