My contribution. While doors are open you have a single M8 bolt holder.

Confused? Open a door and look up.

if its anything like my Grande punto its to bolt the fiat roof rack into..

the thule rack i have just has a pin which sits in the hole...

Wouldn't have expected t inside the doorframe. Doesn't that affect the sealing of the door?

i've seen that hole for the roof rack on a few cars, usually it is plugged with a rubber bit and there is a recess to keep the bolt head clear of the door.

Will get photos later

sits in like this:

I found another one in my new Bravo. There is at the passenger site on the floor a tiny space behind a black plastic thing. It has the space of an ashtray. Really strange small place I really don't know why it's there.

My first thought that it was a hidding place for the Italian Maffia for placing some white powder or something. Who knows more?

There will be a code at the bottom, the VIN number.

Any new hidden features discoverd? I only know the stereo and aircon features.

Aircon features???

Not tried the stereo ones...

Holes in the door frames are for the roof rack - fits no probs (although single-handed fitting both rails and bike rack has led to a few scuffs so I've got touch up paint to fix them!)
