My dads 1997 300tdi has a nice permanant front towbar fitted central extending through the bumper plastic.It came with the second hand vehicle so no provenance,but it does have a TOWSURE sticker on and it certainly looks like one of their basic but chunky offerings.However,the towsure catalogue doesnt list it,so....?
Shame ,I wanted one myself,I supose I'll have to wait until I get a winch bumper and fabricate an off centre one myself
