If memory serves, the Sport Exhaust was something over $5K just for the part - but sounds fantastic. Typical Porsche outrageous option pricing... (great aftermarket units are 1/2 that or less...)
That 2009 is amazing. It's the last year of the 997 and a manual trans car. Even with DIY shifting it can get to 100km/h in under 4 sec.
Like the drop-top of the Boxster? Well, they're not common, but they're out there: 997 Turbo Cabs. I love open cars, but I'd still go coupe as I'd want to spend as much time at the track as possible.
