Chassis corrosion

Not as far as I could make out tim. I got the other tester over and we both looked at it in some detail and also scoured the manual on the VTS.

I would think that the seat mountings/seatbelt mounting would be within  30cm 

If its an old micra the seat belt buckles are attatched to the
Floor. The later ones had them attatched to the seats which would widen the prescribed area making it a fail.
So it would depend on the buckle location
So I would have to agree with GAZ.

Any deliberate modification, excessive corrosion, damage, fracture or inadequate repair not within a prescribed area which adversely affects braking or steering by severely reducing the strength or continuity of a main load bearing structural member.

The paragraph above (rfr)
Really applies to vehicles with a seperate chassis,not saying you can't apply it to a modem day vehicle with integral chassis.
