He got in thru the broken window and without opening the door stole the transparent roof in 30 seconds. The window came out in a single piece? Doesn't appear to be any damage to the car. The "nest" photo doesn't show the C7 alarm lights, just reflectors.
This guy has perfected this operation. Betcha he had some way to practice it a few times on a C7 with the window open before he pulled it off. Very specialized. Unique to the C7.
Assume the cops were called. What did they say? Any other similar reports in the Dallas area?
Sounds like "Vicky Vette" was raped.
