You're very brave to weather this car so much.
Although, maybe you had good reason for it, as it seems there is a crack in the front window, and the co-driver wiper seems to have gone missing.
But maybe this car is modelled after a specific picture, and should have a crack in the window.
The weathering itself looks quite realistic, although the paint you used looks quite orange-y. But that may be an effect of your camera settings.
Anyway. A brave effort. And I think it looks great. Especially the wipes across the front and side windows. Very realistic.
I especially like the way you did the underside with the smears at the front. Great stuff.
