Chrysler hasn't released prices yet. Also, I doubt this will be the last time SRT tweaks the Viper. Remember, the TA is just all the performance upgrades, tweaked shocks and better breaks. I'm curious to see what the new SRT Viper ACR will look like.
EDIT: I guess 2014 could also debut the ACR

Seems like this TA is more of a ACR place holder as only 33 will be released. And the TA was really designed solely to beat the Corvette on Laguna. So, maybe the Detroit or LA Autoshows will debut the 2014 SRT Viper ACR. Keep in mind that the last ACR still holds the American Production car record on Nurburgring and is third overall behind two Ultimas (which don't really count as production cars, in my book, but whatever.)
