This is the venereble 2000GT from where the styling cues have been taken.
There's also word of the LX-F (Lexus Concept) replacing the Supra, sporting a 500bhp motor, making it the only HO offering from the Toyota/Lexus stables, but whatever comes of it, industry insiders have it that the new Supra is set for an 07 return, coinciding with the launch of the new GT-R of course!
