To answer your original question - I traded a Range Rover Supercharged for my MX. Visibility isn't anywhere near as good, for a few reasons:
- The RR is very boxy, so you can see all four corners. You can't on the MX with its curvier shape, and it makes you constantly nervous of rashing the rims when parking. As an aside, the MX is both wider and heavier than even the LWB RR.
- Driving position is much lower. You can crank it higher, but then the car isn't as fun to drive.
- Visibility through the corners of the windshield isn't as good, as the 'A' pillar gets in the way
- The awful heated windshield isn't there on the MX, which makes it much easier to see at night and in rain
- The MX's headlamps are massively better, so you can actually see at night also
- You don't get the sense of "superiority" that you do in a high SUV.
However, it's faster, more fun to drive, holds more stuff, has more comfortable seats (!), better technology (my RR's navitainment was AWFUL), and is markedly more energy efficient.
