Forget the Bose, it really doesnt sound that good.

My only concern on the 2.7 with the 6 spd box is that the gear ratios are matched for the S engines torque and hp. The non S Boxster is more fun with the 5spd as the gear ratios are closer and better matched to the power.

Instead of the PASM consider a wheel upgrade instead.Bear in mind that once u own PASM it owns you forever. No changing to different spec shocks or springs or wheel/tire sizes. The software simply wont allow it. If one of those PASM corner bits - sensors/shocks/modules etc..,fail after Porsches generous warranty you will be personaly making a large contribution to Germanys GNP

There is no convincing argument for PCM except that it impresses passengers and improves Porsches bottom line.
Its really a terribly price to pay for a road atlas.

Im not sure what UK leather prices are, but they are probably close to buying a Korean mini car if you add in also ordering the adaptive seats.

Get the thicker leather sport steering wheel, its worth it

Good luck and kindly do not order silver, black or yellow.
There already way too many of those!
