power wise if u drive a vette and then get into a boxster, u will get a vette.
if u go and test them both trough some twisties ull get a boxster.
i was in the same boat, test drove a few C5s, ehhh, power is there, but thats bout it, all cheap inside and whatever, but hauls ass tho in a str4aight line, but thats now that i was looking for. like everyone else said, test them both and see what u like, but a boxster has that charm and ull most likely end up getting one
