^ speaking of MPVs, that's exactly what I've been driving from my dad... that thing has zero pickup on on-ramps and floats around exactly like it looks like it would. It seats 7, that's the only real good thing about it. If you want to haul bags of concrete or plywood once in a while, while driving a better vehicle 90% of the other times, a crossover is more fitting... and those can seat 7 too.
They still don't have sliding doors, which are awesome especially if you have to do up kids' belts. Only the larger crossovers will take a sheet of plywood (most won't) and they're more expensive than a van. I rather doubt these things drive better than a minivan if that's what they're basically pretending to be without being one.
The MPV has plenty of power on ramps, 200 horsepower in its size vehicle is sufficient.
BTW here is a comparison of vehicle types:

Minivan wins in categories 1,2,3, loses on 4 (very few people tow so it's meaningless), lose on 5, lose on 6 (same as category 4), win on 7, tie 8.
So out of 8 categories, two of which are meaningless for most people, leaving us with 6 the minivan wins four of them and ties on a fifth.
If you have to off road or tow you get a truck chassis (SUV), otherwise the crossover is inferior to the minivan in all but one category. If you cannot stand that your neighbors may think you're a pussy, then get the Crossover.
