Schmengie, are you sure you're not channeling Gottarondo? I could have swore Gottarondo originally made that "lumber" comment, but I guess I'm mistaken. I agree with your comment, although I'm only agreeing to what I think you mean by it (i.e., the vertical flat area below the rear-hatch window looks like it was walloped with some mean piece of timber). I'm not sure if you were also including that as "styling over function," because if you were, I don't see it. I think it would have been more of a styling choice if the Rondo's lower butt had been extended so that it looks less truncated and more pleasing to the eyes of some people. The case could be made that the Rondo would actually be more functional with an extended lower butt due to the slight increase in cargo space--but that would defeat the Rondo's mission of having big-time capacity in the smallest footprint.
I also agree with your comment about the truncated rear-quarter windows, which most definitely is a style-over-function choice (I think Gottarondo mentioned this before, too). But come on, I think most people would agree that the Rondo is thoroughly utilitarian, so the Rondo can't be given a pass for having just one flourish or two? To tell you the truth, I haven't really noticed those two blind spots. It isn't that significant to me, but I can't say for sure why that is. Sure, on paper, you can easily imagine huge blind spots existing in the rear corners, but nothing beats real-world experience. That's just me, though, and perhaps other Rondo owners have a different tale to tell.
Unlike you, I like the "bus-like" driving position. My back seems to appreciate it, plus that upright position gives me a commanding view of the road and I just feel more confident with my back straight and my shoulders back. Yeah, a lot of that is psychological, but that counts too, doesn't it?
