My old L322, the rear seats folded flat and then you could tip them up in to the footwell. This feature removed on the L405 , well at least on my 2013 yr model. First dissapointment since purchase.

My 2017 is the same as yours. The previous l322 was better albeit less room when seats folded. 2017 5.0 Autobiography Supercharged

You have got to be kidding me???!!!! I have had my L322 for 6 years and about to change to a L405. I have just been and tried my rear seats to discover that they DO tip into the footwell! I shall be cursing silently to myself for the next 24 hours that I did not know this 2008 4.2 S/C, Zermat Silver, Grey Leather

Read the above post and thought.... here we go, another 'Homer Simpson' moment, thinking, do mine do that?...............so I went out to the car and YES they do..... Dooooohhhhhh, I have only had the car four years
It took me months to realise that there is a big underfloor storage area in the offside rear of the boot, then more time to realise that I was missing the plastic liner ( Bin ) for it.

Ah well, now I realise I can load more bales of horse / stable shavings in one go, plus I found £3 when I tilted the seats woohoo

Even worse on the 460, they dont seam to think people want an estate.
Still ordered one though. letters not necessarily in the right order
