I got to 115 yesterday on I-10 outside of Phoenix on the way to Tucson. Had a buffer of cars in front of me to give my radar detector a chance with instant on. Anyway, kept it up there for a few miles until I caught up with the group. Was amazed at how it handled, not a flinch at all. But in the final analysis, I have to admit it wasn't a big deal.... I want to find some curvy roads where I can really work the car. Driving fast in a straight line doesn't do it for me.
