Things you found on your car, after a period of ownership

[Zaxxon]

I have just found that my rear seats on my Peugeot coupe don't just fold forward and stay at a rubbish 45 degree angle, but actually fold perfectly flat, if you pull the lower rear seat up and out.
I know I should read the manual etc but I must have missed this bit. However I thought that the rubbish 45 degree design was a French quirk etc. it wasn't until I was lookingvat buying a bike rack that after a bit of sewrching online I noticed a pic of a fully folded seat.

I know, cool story dude, but have you ever owned a car that after a reasonable period of ownership you suddenly noticed a new storage compartment or trick that the car had all along?

Sorry for the thread revival, but the saga continues.
I found out on Friday that I can set the doors to auto central lock at 6mph. And also that the Hazards flash automatically when I brake very hard.

I really should read the handbook
