I paid £50 for a used pair of GTi headlights (genuine) with everything included!
IMO I don't think that they will be new and genuine for under £100 mate, probably Depo or some other copy. Get the seller to send you a picture of the dipped beam shroud, on a genuine part it is a VW logo, on Hella copies a lattice design, and on Depo and others just a nasty metal cover!
