Great overall vehicle

If you are wanting a quiet ride and smooth ride with a lot of standard features. This is the car for you. Pro's - Able to get the pano sunroof in the SLE package as well as the larger infotainment center. Amazing looks exterior and interior. Smooth and quiet ride. Cons Not gonna lie it gets pretty horrendous gas mileage on the 1.5L. Usually after a full tank. Mpg for the trip on a full to empty tank is about 16-19mpg *yes i do have a bit of stop and go traffic* The option not to turn off the autostop feature on the engine when the vehicle is at a stop. Overall this is my favorite car that I have owned. And the standard saftey features are a nice plus

Worst thing I ever bought

23,000 miles and tires are bald. Can't drive it over 50 without the car slipping with new tires. The screen has went out on me twice and it seems to not shift well when first taking off. I'm mostly disappointed in the way it handles on wet, icy and snow covered roads. The rear end sliding and it sways all over the road. If the wind is blowing it is awful. sucks
