For sure the 850/840 has one of the coolest looking interior and also the seats looks just sporty that it speaks for its self. BUT

my first time driving was a nightmare ... the seat has few annoying things, like it doesn't go back enough and the neck support is goofy, I had to add those small black pillows to make up the gap in the neck support.

also it doesn't go up and down like the 5er, I wonder what could be done to fix some of those annoying stuff.

anyone have the same experience? or I have a radical back?
