About to buy 1st Boxster -- need opinions

[SoCal]

Searched the web for info and I found this great site. I'm about to buy my first Boxster and would appreciate your thoughts.

(1) IMO, the 18-inch Boxster S wheels look better than the 17-inch wheels. How noticeable is the difference in handling and ride comfort (feeling the bumps)?

(2) I don't like the look of the plastic wind deflector. How much does it help with wind and noise reduction?

(3) Anybody get the Power Seat Package? My wife will want to drive the car too, and it might be nice to have two seat positions in memory.

(4) I see an option called Automatic Climate Control. What does this option add to the standard air conditioning?

(5) Any other words of wisdom for a newbie?

Thanks in advance.
