well maybe not a gtp, but i easily got the se beat...
and my car was available with everything that the gps had, ccept maybe trac and the passenger air bag.... they had heated leather power seats, power fold heated side mirrors, keyless entry, bose sound system, auto climate control, air refiner, rear a/c, hight adjustable front seat belts, anti lock brakes (88+), tilt sunroof, power rear antenna, computer controlled s-matic auto trans, 5-spd :P, more storage compartments than a post office (glove box, one on the top of the dash, center console, one under the radio one in each rear door counting the ashtrays, one in the knee bolster by the steering wheel, one in the rear self), trip computer with information center, then the second gens had built in phones, memory seats, VIS intake, navigation systems, memory seats, 6spd trans... and keep in mind, the second gen was in 91....
anyway they are two totally different cars, my acura is a luxury sports sedan, and the grand prixs are either family cars, or road rockets, depending on your model... so basically its comparing apples to kiwi.... oh and my car was 19k new
