Went from a 2007 Civic to the Sonic.
Got a good deal on a 2LT ($16,500).
Now at 5k miles on the Sonic.
Handling is solid, though I've ordered some new tires to get rid of that squishy ride that I attribute to the stock (soft) tires.
Gas mileage is on par with the civic (~30 MPG mixed).
If I had a lighter foot on the highway I'm sure I'd get the rated 35MPG and then some.
Features set can't be beat in the price category.
Only the Kia Rio (?) comes close.
What Edmunds fails to stress is that dollar for dollar you get much more with the Sonic than any competing vehicle.
Stereo with bluetooth, sounds decent if you tweak the EQ settings, easy to sync with iphone
Seating position (higher than most sub compacts)
Trunk is huge for a sedan
Right arm rest for driver is uncomfortable, mounted too high
Transmission shifts from 2nd to 3rd gear too quickly and causes the car to bog down.
A CVT with the 1.8L engine would rule (hence - the Chevy Cruze!!)
