Mach, read my first post that kicked off this thread...
3.4-295-250-07
Eslai heard the same thing from the same dealer (Pioneer). Other dealers have confirmed this as well (as read on Rennteam). It obviously doesn't behoove the dealers to be advertising the increase, when they have gazillions of unsold '06s on the lot. However, for whatever reason, some have chosen to be forthcoming with the info.
I'm not sure why people are so surprised. Power increases are in keeping with the evolution of the 986 and needed (and then some) to keep pace with the competition. Boxster owners know that the current models have good kick, but to the novice roadster shopper, 280 hp looks...lacking...when compared to 333 (Z4M) and 355 (AMG SLK55).
I guess we'll know soon enough. My Rep is going to email the 07 order guide when available, and the 07s should be on the lot in the fall.
With regard to the Bose system, my understanding is that the principal deterrent to a post-purchase install is the replacement of both door panels.
