Buttoned down ground pounder
 I find the car a real kick in the pants to drive. It is refined when called for but hit the m button and hold on . What a monster. But this car is the most precise and accurate steering car I have ever driven. It corners like it is on rails. Roll into a tight turn and Punch it and it just hunkers down, rolls out on azimuth, and jumps out like somebody kicked it from behind. Lots of cool cars on the street with wicked exhausts. But you can take em in this car. If you have turn nothing but a pure supercar can keep up. The transmission takes a little getting used to but bottom line. I love it! Acceleration is smooth, fast and predictable.
