I'd venture to say it's VERY expensive even more so than that of a similar Buick especially if you're dealing with the builders/tuners involved with the Vipers (Heffner, Doug Levin, etc.). Most of the ones I have seen down here at the Vette/Viper shootouts did have all the safety equipment to run in the 8's or faster but there where plenty of them in the 10's/9's that didn't have any safety equipment kinda like you see with our cars especially at BG:wink:
