the lines of the G20 do make the rear of the car bulge beneath the shoulder line, akin to the F32 4 series. I loved the F80 rear arches and I love the idea of having them again on the G80, but from the side, the lines make the transition look a bit funky. They still look good from the 3/4 and rear view, but something looks off in the profile... probably something you have to see in person. Certainly not a deal breaker; and like I said before, I'd rather have these than non-widened rear arches at all.
