from what I can see, looking at a regular image of the srt, it lloks like they removed the rear windows, rear door. they also removed the plastic black pieces that run across the top. the side mirrors look diferent. it looks like it has heads up display. The overall caliber has been lowered, different rims.
They tried to make it look like one of those delivery vans by removing the rear door/windows.
They added a sjideskirt as well with vents.
Don't know if I like the color combo but it looks different, and different is good sometime.
It is better than what I can ever do cause I cannot do images like the two above images.
