Don't know, but these days, I always seem to be in a rush. Heck, even if I am not in a rush, I always seem to be ragging the car to death. I can't seem to help myself. I keep telling myself to change up, but don't. Fuel alone is killing me at the mo - 25mpg. Its no good. I may need to drive a more relaxing car. I am safe - but far to fast & far too stressful. Maybe I need some more relaxing music?
