The X6 is a car designed not to appeal to the "average" person, therefore the "average" person won't like it.
I'm an early 30s single guy and the X6 is EXACTLY what I need - fast, handles incredibly well, can take me and three adults to the mountain, and doesn't look like I've taken out two child seats to do it.
It *is* however, a controversial car - the Top Gear review parody demonstrates the popular opinion that doesn't "understand" the X6.
Ultimately - who cares what others think tho? If *you* like it, and you're happy with the future residual (which is VERY good) then enjoy
