If I could only have one, I'd get the Cayman S over an M3. I think the Cayman is a fun drive and quite forgiving to an inexperienced driver. If I could add a asecond car it would be the M3 or the RS4.
I have never seen a chick driving a Cayman.
I have not seen many chicks driving Boxters either.
Not entirely sure where this stereotype came from?
