No problems whatsoever, although its only been 14 months and 10,000 miles so far. Seems solid and well made, for a car in this class.
I get an average of 40 mpg without driving like a granny. That number goes down to about 36 mpg in the winter due to the addition of ethanol to the fuel at the pump, which is frankly a rip-off.
The car will come to a stop when you want it to. A dumb dog wandered out on the road, I stomp on the clutch & brake pedals, I avoid running over rover.
