Given that I drive a Diesel daily I don't understand the reluctance. Often when people ride in my old Dodge (it's a 2002, old tech) they're amazed at the smoothness, power, quiet interior (pretty loud outside!), and lack of odor. This speaks to what they ARE expecting. And I always explain that the new ones are even better. Many seem to come away at least with a more open mind.

I'm guessing that the biggest impediment is the lack of exposure to new-tech Diesels. That's partly because they might have been around a newer Diesel but they're so smooth, quiet, and odor-free that folks might not even know that they were around a Diesel.
