I'm not sure I see the point of this thread. Lots of cars are faster than a Boxster or Z4. The magic to both cars are how they drive. A couple of years ago, I drove my crossfire back to back with a Z4 3.0. The Z4 is just a more visceral and rewarding drive. That makes the car more fun to drive. Even when you look at mercedes badged cars vs the BMW competitor, the BMW typically gets the nod because it's a better car to drive, even if the Mercedes is faster. And the Porsche? I drove a base boxster a number of years ago, and it was amazingly fun. That car was designed for the pure joy of driving and nothing else. IMO, the best part of the crossfire (that's it's a mercedes that's much better looking than almost any mercedes) is also it's achilles heal when it comes to driving dynamics. But hey, for the price our vehicles go for, it's hard to do better.
