People noticing the amount of diesel cars now on marketplace?

I understand FBs algorithms if you click on something the bot suddenly assumes it's what you want and increase the results but I can't help but notice the amount of diesel cars in the last few weeks that are in marketplace.

Some are very optimistic with their pricing but some are downright bargains.

Not just Hilux, isuzu and Rangers, it's a lot if Euro cars, Territorys, and Korean stuff.

My friend is trying to sell his tidy 2019 Mondeo diesel, he bought it 5 years ago for 18k, it's listed for 8k with 150k on the clock not a single enquiry. He wants to go electric.

Just think with the diesel price out of control and it probably will never return to parity with petrol are diesels a thing of the past as a family car?
