Your wires are nice and clean, you do have some pinching on those fenders tho.
You've got that pole/star where it transitions from the side panel crease into the fender and you're bending around into the wheel well. What you can do to alleviate that is add an edge on either side of the star, so that its more or less restricted to one plane, and not being pulled in too many directions.
I attached an image [hope you don't mind] to better illustrate what I mean. Hope it helps.

Sometimes you can get away with pinches that are obvious in Modeler, but don't really show up in a render, but I think the one you've there now is a bit too much, and likely to show in the render.
Overall, its looking good tho, keep it up.
