I get SERIOUS thrumming and pulsation with the sunroof open and lowering the rear windows slightly eliminates this completely. AFAIK the rear windows in the 2 door do not open so that could be a major problem with a sunroof equipped car. An owner from Australia said they get the 2 door but no sunroof option, don't know if that is the case in other markets....anyway the sunroof is a big deal to me since this car replaced a convertible so I'm OK with 4 doors since the whole package works better for me and the 4 door look is growing on me also.I dunno if its just me but ive grown to like the 4dr better than the 2dr...anyone else feels this way?
