What is the difference between a Stealth and a 3000GT?

From 3SI Wiki

The Stealth is the American cousin to the 3000gt.

The Stealth was build by Mitsubishi and imported by the Chrysler Corp. They differ only cosmetically, (and a few options such as Active Aero for the Mitsubishi's) The power ratings are the same for all the corresponding models (Base/Base, ES/RT/SL, RTTT/VR4)
