I have owned my 2013 Accord Sedan for 8 months now, and overall, I am very satisfied.
The car handles very nicely, is very comfortable (I am 6'2"), looks great, accelerates nicely, is quiet, and came with lots of great standard features, like the bluetooth and backup camera.
I have drive mostly in the city, and mileage is okay - around 24 mpg. However, highway mileage is great - around 38 mpg.
I have experience the CVT stuttering mentioned by other reviewers on occasion. It is not that bad so, at least in my car. However, Honda really should address this issue if lots of buyers are having a major problem with it.
The environmental controls are not convenient. I have to look at them to turn on/off the air conditioning, adjust the fan speed, open/close the air vent. I much prefer the Toyota Camry's round dials, which are much more intuitive.
Honda should address the CVT stuttering problem.
