I have the ss model which is great. Plenty of room Nice seats and this car drives real Nice and handles the road as expected if not better. As for gas its good but you don't buy the ss model for gas mileage right. I really enjoy driving again. Oh and I drive all day at work. If you buy an impala get the ss you wont be disappointed.
power and handling. interior works well
sun roof on all impala ss models,and a lock for glove box with a light
