right guys my car is pretty solid all round etc however i noticed today when i pulled my rear seats up there is two very slight holes either side of the car where you can seethrough and see the floor.

they are small holes, i say holes they are like lines not even the size of a 5p piece wide, i hit the area around them and nothing fell apart it seems pretty solid - just these holes.

is this common and is best way just to have them welded up?

oh yeah iv even pulled all the carpet up in the boot etc and thats totally solid.
