this is what usually distinguishes a sports car driver from a guy who just reads about them (or just looks at the pictures!) in magazines.
Roadsters are Roadsters
Coupes are Coupes
They serve different purposes.
A guy/gal who buys a Boxster wants two seats and purpose built top down fun without compromising performance. He'll consider a BMW Z4, Honda S2000 and AMG SLK.
A guy/gal who wants a non-turbo/gt2/gt3 911 probably needs a back seat and has kids and is probably older. He'll consider an Audi S4, BMW M3 or one of those Jaguars.
Whenver I hear someone say "Boxster nice but no 911" I know I'm talking to a guy who probably has never taken a trip around a track or autocross and the discussion will turn to styling vs. performance.
p.s.
On Styling I'll give the edge to the 2002-2004 911 over the Boxster.
The most beautiful 911 yet, in my opinion (would never be confused with a VW)
But good luck ever convincing me to give up a mid engine car for a rear engine one.
If Porsche made a mid engine AWD(with ZERO understeer) 911 I would never want another car. Well maybe I'd keep the Boxster for sunny days
