Special offers for diesel cars?

I don’t know where the topic might fit in better. If not, I ask for a postponement to another forum. Supposedly, the diesel demand broke in. In fact, even during test negotiations in the local car trade, I did not mention acceptable payment prices for my Euro5 diesel and this was justified by the demand slump. However, what I did not get are good offers when buying a diesel. One should assume that the Hers How, if not by offers that make a diesel seem attractive despite the existing uncertainty? Has anyone noticed that certain dealers or manufacturers promote the diesel sales price or is there the need to accept price reductions so far only for private individuals who want to get rid of their used cars?
