Wow, I got mine up to 121 mph the other day, but had to ease off the gas because my exit ramp was fast approaching. My car could have gone faster and I was going up a slight incline on the highway. The problem with testing the max speed is my fear of the police (yes officer, I'm late to work) and the fact that you cover so much ground so quickly. I've only gone over 100 mph on the freeway maybe 3 or 4 times since I've owned the car for 10 months. Obviously, I do this only on an almost empty freeway-I'm not interested in wiping out a family over stupidity.
