I don"t feel it is, I could get a slightly used C6 Z06(hopefully next for me) and a Golf R for that much. I'd get more use out of both of those as well also. I love SRT, and it's a wicked cool vehicle, but no thanks.
I drove a 2016 SRT8 Cherokee and I was blown away by how fast something that big can start and stop. They claimed 0-60 in 4.5, that exactly what it did. But even that Jeep was almost $70k with options....
