Is there a real world (i.e. not track) noticability between a 2002 Boxster S with 250hp and a 2003 base with 228hp? Both are tiptronic trans. I know the S has the upgraded brakes and everything and I wanted the S, but I found a nice 03 Boxster base with the exact color combo I was wanting. I was also wondering if anyone has installed a subwoofer in their Boxster? I don't want a huge system or anything, but I am a bit of a, as my gf would put it, a "music snob." I don't want something that others can hear booming at a stoplight, but I have a 10" in the trunk of my current car just to round out the sound and I have become quite fond of it.
