3000GT VR4's and Stealth TT's are considered cousins or bastard step-children of the DSM community. 3.0 liter parallel twin turbo, 300 horsepower, all wheel drive. The 3000GT VR4s came with all wheel steering, some but not all Stealths did as well. Both cars from 1994 on had a 6-speed transmission and 320 hp. Stealths were better for drag racing since they were lighter (less toys) while the 3000GTs were just plain cool with all the gadgets.
Both cars were made on the same assembly line; it's all a matter of who's name was stamped on it at the end plus a few toys here & there. With equal options though, Kelly Blue Book of course considers the Mitsubishi version much more valuable since it's a smoother, finer, and better built car than a Dodge.

Same goes for a Talon vs. Eclipse, Talon is usually a grand cheaper than a matching Eclipse. But that's ok because the Plymouth Laser is another $500 under the Talon.
