Thank you for your kind words and support! Happy new year aswell to everybody!
As seen on the pictures, the underside ( and trunk ) has been painted, to a dark grey colour. I've also drawn some circles around some holes. I dont think it would be smart to leave these like this, but cannot recall if they had something in them from the factory or not? Ofcourse i mean only those that are just holes, not the ones meant for bolts.
