I agree with Blue2000. You should drive them both, and make an informed decision from there . Otherwise, you'll end up cross-eyed trying to sift through all of the opinions and advice here on the forum regarding which one to choose. Personally, I would recommend buying the best kept, lowest mileage, well maintained boxster that one could afford . Good luck !
p.s. When it comes to choosing a color, you'll find that there are only two possible scenarios - Speed Yellow or wishing that you had chosen Speed Yellow .
