Very nice car
I think the fuel consumption is high
That isn't much of a factor with super cars, I have heard a lot about these vipers, mostly that they are terrifying and hard to control. These take some experience to drive.
That was true about the older Vipers, but the newest ones (2013 and newer) have traction control and electronic stability control so they're very driver-friendly. Of course, driver can partially or completely disable any of the nannies if they so choose.
