If I were to guess, I would say they simply used a '96/'97 Viper photo and grafted the ACR wheels onto it - and changed the stripes to silver. Not only does it have foglights, but also foglight covers. I can't imagine the covers would be coming back for one year, especially given their tendency to pop off on occasion. My bet it is a '96 GTS photo with the ACR wheels added. Of course, I could be wrong!
