The color looks fine to me.
However, saturation shouldn't worry you a lot, as you can always change it easily in the end with the brightnes/saturation filter.

What I miss are some reflections on it. But I would do those when more of the side is finished, so that everything matches.

Looks awesome!

The window looks great! And the brushing on the skit handle look Good imo, but you should brush the majority of the car first, in that way you Will get everything to blend in nicely, keep it up, it have alot of potential

I decided to restart to chop, sad. Thats what I have now :

Fine Scirocco is coming!

The background is gorgeous!

As Ice Devil said, the background is awesome

Can't wait to see more work on this
