What happens if one of those things rolls over and lands on its roof? Is there some kind of structural support or does the entire cabin collapse in on itself?
I grew up in a town where large families were common so these (and the Chevrolet/Oldsmobile flavours) were everywhere in the early 1990s and completely gone by the late 1990s. I have to assume they were of poor quality even by old GM standards, or the kids who rode them in elementary school would have taken them as cheap first cars in high school.
The GM U-Body, one of the prettiest pieces of crap ever released.
If I recall, this is based off the W-Body car platform, which was already challenged with things like front suspension alignment and integrity, and adds even more weight.
This went on to underpin the underwhelming Montana/Uplander/etc, as well as the Aztek.
