There it is not only an identity by semantic similarity based on the term  "extraordinary"  express in the writing and implied in the right side offer ( not visible here): The used car that you have dreamt is only Autoexport, and an identity for spatial contiguity (the writing within the image and the first line of the offer).  

But there is a hidden opposition (the dinosaurs or the monster of Loch Ness does not exist). This opposition consequently drags an other more dangerous identity for syntactic similarity (as dinosaurs or the monster of Loch Ness, so doesn't exist some extraordinary used car ).
