Can anybody tell me why I'm getting a great render in the preview, but terrible black patches and modifiers such as subsurf not appearing on final render? Below are pictures and .blend file. I've tried applying the subsurf but am still getting terrible black spots.

I appreciate the help!

enter image description here

Here is the .blend file:

    $\begingroup$ I've downloaded the blend file, but the textures don't come with it. You might want to go to your blend file and go to File > External Data > Automatically Pack Into .blend and reupload your file. $\endgroup$

Thanks $\endgroup$

So I solved it myself, there must have been some type messed up topology that was allowing it to preview fine, but then when I went to actually render, everything went haywire. I ended up re-modeling all the bevels around the initial shape and now it renders out fine!

So I guess make sure to do periodic test renders!!
