Yepp, funny!
As far as I know the models of Vette 'n GT both have been initialized by Bill Mitchell of GM headquarters. Finally a German named Erhard Schnell has done 1st drawings for the GT, only then the guys found the old fashioned Stingray should be updesigned, too.
So, nothing to do with "Baby-Vette" and so on...
Keep on Opeling!
