Getting rather off topic, but the thing that annoys me about the G60, is that it just looks ungainly.
The details of the graphics like Angel-eyes, Kink, Kidneys etc can be changed with a facelift.
Its the sheet metal that just looks awkward and bulky and kinda doofy - though I understand that is because the car is designed for mixed drivetrain options which will fundamentally alter the physical structure of the car. In the flesh its absolutely massive, but not in an appealing way. Its almost as tall as a Kia Niro; a small crossover. And its supposed to be a sporty sedan.
To me, BMWs are about clean, crisp lines. They're kind of menacing, but composed. I've never liked their designs when they've added so many cuts, and creases and angles and shapes. And then you add that to a awkwardly shaped body, it doesn't scream particularly harmonious design to me.
The NKL i3, 3 series and iX3 are a perfect demonstration of exactly what's wrong with the design of the G60. An NKL-inspired facelift will help the 5er a lot, but it still won't completely rid us of those awful proportions.
This is of course, all subjective.
