Just bought the 2011 Mazda2 to replace my slowly dying 1999 Nissan Maxima.
It is awesome.
The savings on gas is unbelievable.
I drive mainly around town (work commute is under 4 miles on surface streets) and it handles beautifully.
Contrary to the "pro" reviews, I don't find the engine noise loud and the acceleration is fine.
This car has everything I had in my Maxima with the exception of cruise control (I wasn't interested in paying extra $ for fog lights, cruise control, and red seat piping on the Touring edition).
Oh, and did I mention, my 16 year old thinks it is awesome!
Placement of dials and controls.
Put the door lock control on the door - even the guy at the dealership had trouble figuring out where the control was.
