C'mon Cool Cool, after that 'rain going inside the car' debacle you should know better about posting stuff like this. That means nothing, let's wait for some official release..
PD usually needs the car's stats and measurements, and engine details etc to get the car to work like it should in the physics engine. You would have thought they would be asking the people behind it for the data
Can i just ask where this "rain going inside the car" subject came from? It sounds like you're saying it came from CoolColJ's "insider" quote, but i can only see he says about the rain droplets on the windshield casting shadows onto the dash inside...
Just about to post that, i'm loving this, looks awesome, and i was also about to say, that i'm hoping this garage will be 'your' cars, depending on which you drive the most often etc..
