I bought one new back in 2015. the first thing I did was get the windows tinted and a good wax put on. I drove it for a year and noticed the paint was wearing of the leading edge of the rear quarter panels. I went to the dealership and they told me it was "normal wear and tear." what a bunch of crap. paint is not supposed to wear out after a year of driving on the road unless it is poor quality paint or the engineering is pathetic. I ended up trading the car in on a 2008 Grand Prix GXP, but if I hadn't, I would have had to get the car repainted. the permanent fix for the low quality paint is to install mud flaps.
Another thing I didn't like about the car was the size of the seats. when you sit it one, make sure your butt fits. I'm not a big person, 5'11" and 245 lbs, but the shape of the seats wasn't good for my butt.
They do get good gas mileage, but they are built cheap and are not that comfortable. Another thing I didn't like was the back seat, if you put the front seats all the way back there is no leg space for people on the back seat. probably worse than a Camaro or a Mustang, and that is with a 4 door sedan.
