I could see where they could invest that much into that car. Not that they should have, but it's possible. If they have absolutely NO DIY ability then they are stuck paying gobs of labor for any little thing they want done. Plus paying retail for the parts/materials can add up quickly. When I was in the stereo biz I did several systems that had $1500+ worth of wire in them.
That is honestly a WALL of subs and speakers behind the seats.
I'm still a neighborhoodASSHOLE!
