both cars r perfect (as most european ones)
but!
boxtster is targeted on lower segment (why the hell it's so darn expensive??? it's like 120000 DM here!!!)
carrera is top car with the best ingine & transmission.
if u r mad after speed and adrenaline - go for carrera
if u want great car, but don't want to bother with maintance - go boxter
surely check all issues, like warranty, insur. etc.
take a drive test if u can man! that's very important
good luck with any choice. both cars r great.
