To contribute some rough anecdotal evidence, when I look out the window next to where I'm sitting this exact moment I see a mix of newer and older Honda Civics, Toyota Corollas, and some older SUVs. Judging from the age of those cars, I'm going to guess that most of their current owners bought them used and not new. I do not see a single pickup truck.

I'm not going to debate that the Ford F150 dominates new vehicle sales in north America, but that's only accounting for the preferences of people who are buying new vehicles and doesn't track what the used market would buy if given unlimited options.

As for the marketing argument, there's plenty of discourse surrounding it. Most new pickups are sold with short beds and extra features which make them impractical for use by many commercial trades that do use pickup trucks. There's a question of whether the F150s popularity is because of the truck's utility or because of the aesthetic desires of purchasers.
