Jon has a Sapphire Blue GTS the last I saw, he did have a black GTS.
YouTube - Jon Bon Jovi y su Dodge Viper GTS
Jay Leno has 2 vipers, 96' GTS and a 93' black RT/10. The RT/10 was given to him by NBC.
Interesting post from Jay on his message board:
"No, I don't have the first Viper or the first Prowler. I thought I had the first black Viper, a 93 model, but Tom Gale actually got that one. And I have a very early 96 Viper Coupe. But, no, I don't have the first of either of those cars. Prowler should've had a V8!"
A few Nascar drivers have vipers (Kasey Kahne, Kurt Busch, etc...)
NJ native, Ray Evernham, recevied a 96' GTS as a gift from Rick Hendrick when Jeff and Ray won their first cup championship. I think he has one more Viper, a Prowler and several Motorcycles. By the sounds of it, Ray's GTS isn't stock.
"I had the Car of Tomorrow before it was the Car of Tomorrow," Evernham said as he looked at the wing on the Viper.
Chad Pennington of the Jets has a steel gray GTS if I remember.
I never, never got around to asking Keith Urban if he has one, yet he has a sapphire RT/10 in "Where the Blacktop Ends". I met him along time ago, awesome guitarist.
