Mainly happy
 I've been mainly happy, when you treat the thing like a motorcycle and bang off the redline at 6,000 rpm in 1st thru 3rd it works not too badly.  Engine slow idle is a bit lumpy, and it lacks a bit of power with the a/c on.  Absolutely must have 4 good snow tires installed, it's very light and it steps around quite a bit even on wet pavement.  Great gas mileage, lots of room and functionality.
