Don't worry, I know about the seams. I haven't tried fine tuning the smoothing yet.
Here is the problem I was having with the grill.
I am trying to make the cavity in the grill. This is the geometry I used first.
Producing this stupid shape.
So I was like "fine" I will do this...
And I got these massive pinches!---All Quads!---
I need this truck done by tuesday so I half assed it with this.

See the cavities aren't nearly as deep as they should be.
Any suggestions?
