Tesla.. without a shadow of a doubt.
Along with my German and Italian stable. I wouldn't own one of those if someone else's money paid for it. I value real performance. Any schmuck can make a car go fast in a straight line, it takes real engineering to make it go fast around corners. Lets see that hellcat hit an 30' apex at 85 without rebounding and sending its driver nose first from pushing into a wall. Granted, american cars have gotten better given most of them are now tuning at the 'ring.
As a racing instructor, if someone brought that thing to watkins, limerock, vir, or pocono, I sure as hell aren't going to instruct in it. That much power and no road manners = instadeath. Ask the owners of the carrera gt's.
Rob, For someone who has owned an exige (I think or was it an elise), i'm shocked you would ever want something like this.
