Because we see them for what they are...insanely useful/practical/versatile tools. are too focused on image.
I don't even have kids and I want a van for comfort and utility. I wish there were high roof models that could be used for a camper conversion. I saw a wheelchair converted Sienna on FBM the other day with a medium roof on it and was really tempted to look at it for a camper van conversion. Ultimately I had some weird guilt about taking away a rare vehicle that someone might actually really NEED, but I'm on the lookout for something like that. The wants are growing.
