My brother just bought a 2008 porsche boxster, I know that the cayman is a faster car but the boxster handels a little better. That boxster can get up and go so much faster than my crossfire, so I could imagine about the cayman! But there is one thing the crossfire can do better than the porsche and thats turn heads! After my brother bought his porsche he said he should have got a crossfire because all the compliments and head turns i get in my car! hahaha I love my crossfire, but porsche makes a very slick car! I love my car and wouldnt trade it for anything else, but I do enjoy driving my brothers boxster every once in awhile! hahaha
