I've had my 2011 since June.
No Regrets. Love the car.
Have a few small annoyances that I will bring up with the dealer on the first service, passenger cup holder is not level. The whole trim piece is off by a few degrees. And, i have a strange tick/click noise coming from driver door that happens when i let off the accelerator. Thought it was trash in my storage bin on the door but after cleaning that out the noise persisted.
Anyway... I did find a way to bump my MPG in town. I have been manually shifting for all of my city driving (i drive 80% city, 20% highway). I do downshift to 1st when at full stop. When accelerating I generally shift by 1800 rpm. At 40 mph I am in 5th with my MPG indicator between 40 and 50.
I am hauling my kids most of the time, so I don't need to get from A to B as fast as possible.
On my current tank I have 330 miles on the trip odometer with the guage reading a few ticks under 1/2 tank.
