The exterior photos aren't flattering by any means.
Way too many reflections.
It is hard to photograph a black car outdoors without some reflections. But there are so many in the ad snap shots that it is distracting and doesn't show the lines of the car.
Try an overcast day with the car far from anything, or in the shade of a wall / building.
