Yes, it looks much nicer than 2014 Impala. It is good to hear that the trunk is big as usual. When I rented 2014 Impala in last DEC,I managed to put 3 medium size suitcases (and there was some room left) to the trunk.
2014 is the first year of the redesign (so 2105 is the second), but there's still some of the old style that are "Impala Limiteds". That's apparently going to be true for another couple years. Don't know if anyone has seen a 2015 Impala Limited, I don't look at that style close enough to figure the year out

. If you see the word Limited on the back of an Impala, run quickly the other way.
