To fit them after the car is complete :)
It should be fairly cheap to get hold of some side facing fold away seats, there is quite often guys on the forum breaking discos
I have a toolbox that needs picking up from Doncaster and I want to get it to devon, it doesn't have to be a straight run I can probably get it from anywhere on the m3/m4/m5 corridors as I travel to London and the channel tunnel quite regularly
Many thanks billy
