Second, Boxsters, especially the newest ones, are serious machines. And they are also built much better, and from nicer materials. And if you really want the best Porsche, the current star in the line-up is the Cayman S. Basically a coupe Boxster. Does 0-60 in 4.1 seconds.
The "star" of the Porsche lineup is most certainly not the Cayman S. Fine car, yes (Cayman GTS is better).
The 918 is the king but at almost a million $ you won't see many driving around. Luckily there are plenty of 911 Turbo S and GT3's running around. Those are the stars.
