Northern,
I'd go with an SUV, if I were you. Yes, I know they're gas guzzlers, etc., etc., but given the three options... (Then again, I don't have kids, so perhaps my opinion would differ if I did, although I
seriously doubt it.
) When one of my sisters-in-law had her and my brother's second child, she also wanted to get a minivan, much to his dismay (he'd always been a sports car and motorcycle kind of guy). I hate to tell you, but he lost the debate, and they now have a minivan.
Along with FunGirl's "Friends don't let friends..." quote, you might also want to remind your wife that minivans are called "people carriers" here, as balmerhon mentioned. That in itself should prove a deterrent. (I might be mistaken, but the last time I checked,
all--or the vast majority of--vehicles were "people carriers." It's akin to singling out, say, houses from other types of dwellings and calling them "places where people live." Sigh. A statement of the obvious...).
