I could not live without the fold down rear seats, they are great, I did not have an option at the moment I bought the car (That was the car I wanted and it came with the option), so the sales agent made a discount on those and they came almost free.

I recently got married and there's no way we could have moved so much stuff (Gifts, bags, etc.) around without the seats folding down.

Also I got my new set of wheels and tires this weekend and I could not have moved those around from my home to the wheels shop without the option.
If you can, get them, they come in handy

This is one of the occasions where your salesman is wrong. This is my third 5-series with fold downs. Never had a problem with any of them.

The only (minor) issue is a wind 'buffeting' if the seats are flipped down and the sunrooof (only the sunroof) is open fully...
