Yes, it's really odd to have something so minimal but effective, at least in real life, like a car wash, without a car with dirt on it.
I do recognize that I drove some laps, I think 6 or 8, in Toscana with a Citroen Xsara and the car went really really dirty.
I did the same with Loeb's Citroen, and the car took 2 hits to the wall to lose parts and get dirty as well.
But then it comes the weird part:
I went to the replay section to take some pictures of both time trials. I don't really know if it is because I always play with heavy damage (especially online to have drivers who race clean) or is it because a random and unknown reason of the game and PD, but if I forward the replay to the last lap, the car is PERFECT. But I mean, JUST PERFECT.
I have to wait until that moment comes to see the dirt and the damage.
Anyone knows something about it?
