As long as it was an excellent product, it could be called the Porsche Puffinbarger, Quackenbush Edition and I'd be okay with it. Honestly, I always thought Box-ster was a little bit contrived anyway (love the Dilbert cartoon btw) but it never really bothered me.
When it first came out my friends and I felt the Boxster was a cool retro throwback to Porsche's roots and thought it should have been called the 356D or something. (that's also why I never listened to the people that tried to argue it was just a cheap 911, or only for those who couldn't afford a 911).
If they rename it the 718 I'll be okay with that too. But that's just me.
