I would guess it is a liability issue from the mfg. if case there was an unfortunate accident down the road and someone got hurt from the seat bolt that was replaced broke.
Someone recommended some time ago to try Eagles-Hell Freezes Over-1994. I also agree with the song selection with a good stereo system. I grew up with this song but unfortunately I'm still waiting on my Limited to arrive so I can play it with the B&O system.
