can someone help me out?

I don't know much about photoshop but i've seen some awesome work by some of you guys. I got a favor, could someone photoshop this from this gray color to black with tinted black windows? I don't know much about it, but i figure it couldn't be that hard.

uh, ok. I got this pic off of another thread and if they can get it uploaded, how come i can't? It should be the same size file right? anywho, i'll just put the link:

It's the first darker gray civic.

Here you go.
