After owning an Acura Integra for many years, I thought I would love an upgrade to the Acura RSX. I test drove two RSX's, and decided against buying it (I got a Subaru Impreza 2.5 instead).
Everything seemed good for the RSX on paper - good reliability and fuel economy. As soon as I test drove it, I knew the RSX was not the right car. The automatic trans seems sluggish (compared to the auto trans in my old Integra). The brakes felt mushy and non-linear. I felt they would not stop the car in time (the Integra brakes were great). Steering felt okay, but everyone knows that the RSX has a terrible turning radius.
Worst of all, the cabin of the RSX felt cramped. Too bad, because I really wanted to like this car, and it looks great from the outside.
