This is my post and I totally agree. I have a great mechanic and he is baffled ,too. A leak of any type would be isolated to a spot. Even if it spread out,it would not exactly cover the entire bottom of the vehicle. If it were purely condensation based, it would be pure water with no oily feel. When I backed the car up, it looked like an exact wet shadow of the shape of the csr,with dry areas only were the tires touched the ground and a two foot by one foot dry area under where the gas tank is. This is so weird!
