Don't let yourself get "caught in the Crossfire" 
[:0] as, for about the same money, you can get a new Nissan 350Z...

...which has considerably more power (287hp/274 ft-lbs. torque) and seems to have a larger/bigger interior. [8D] If the Crossfire is a "true sportscar" (???) then [u]why did DC
only put a
215HP non-turbo engine in it</u>? [V]
Keep your PTC, and, if you must upgrade, wait until the 2006 model year and do it then--new PT Cruiser design, even more power, and practicality which really does matter (to many of us).
Just my two cents. Good luck.
