Yeah, I remember a co-worker of mine had to shop around forever and finally have a minivan shipped from out of state, because he and his wife researched and it came down to one model (Honda, I think?). Anyway, virtually everyone else wanted it, too, since it probably was top-rated by Consumer Reports or whatever, and local dealers were charging 5-10K in markup, or more.
So they are not necessarily cheap, especially for the ones others want, and they are not something that are going to get you laid, LOL. I definitely blame the boomers for starting that whole thing, though. For some reason it became a thing where lots of parents want to give the impression they....are not parents. I guess these people thought even though they had kids, they needed a cool car to pull tail? Or be the hawt MILF? What are these people even doing? They are parents! What is this denial bullshit?
For some reason, the very same people that will point and giggle at some older guy wearing a baseball cap and driving a Corvette because he's bald and who does he even think he is - will turn their nose up at driving a minivan even if they have several kids and spend their time in their vehicle carting kids around and getting groceries. No, they need something like an SUV, because....reasons. The same reasons they accuse the guy driving the Corvette of!
I was just searching around on cargo space vs. full-size SUVs, and at least in some cases, the minivan (Honda Odyssey) has more than at least some of the full-size SUV models. They definitely have more leg-room and head-room than full-size SUVs I've been in, when it comes to the second-row seats, anyway. I figure one of those behemoth Escalades might have something comparable, but I've not been in the back of one of those...
