According to Carfax, the pre-delivery inspection etc was done on 04/29/14 and the car had 8 miles on it at that time. So I guess sometime in March/April?
BTW your pictures of the car inside the dealership don't look all that tinted, it's the outside ones taken with the camera phone that do. Maybe all the reflection and the angles? For example look at my car from two different angles...in the first one you'd think I have limo tint by how dark it looks but the second one isn't nearly as dark.
