Purchase advice Omega B 2.2 16V

Somehow the information about this model is very scanty, which suggests that most people are satisfied with the box… I got a Bj01 in the short choice. What I’m surprised, however, is the gap between the cockpit and the body on the driver’s side. There is a 1cm wide gap through which you can look inside the car. Unfortunately, I only have a photo from the left side, where it can be seen a little bit. the previous owner maybe only, e.g. when retrofitting the Navis and Bose system slammed? I noticed that the Bose loudspeakers were integrated into the hat rack (is not a caravan), can the original be? I only know the Bose system from the caravan where you can find the subwoofer rather on the left rear wheel. Tomorrow I will talk to the seller again and would like to hear your opinions in advance.
