I would guess its the price point of the Q more then anything. I have looked at them a couple times. I just cant get over the exterior styling on its nose or I would probably have bought one.
There is a whole lot of bang for the buck with the Q now days, especially with the pricing GM has on its new generation triplets. An Escalade's hitting 90s and Denali's in the 80s, then the LC in the 80s and LX in the 90s. That Q is a bargain. I think people are starting to catch on. I see a lot more Qs on the road now days.
I really hadn't notice Q being larger then the LX. I sure didn't think it was Sequoia size.
The sequoia is about the largest SUV on the market it is in width, Other then the Suburban sized GM triplets and the Ford Expedition EL Twins are longer, The sequoia is actually wider and almost as long I think the Sequoia sort of splits the difference in length with std length GMs/Ford VS. the long GMs/Fords.
It has always been my understanding that the Q was the US version of Patrol the main competitor of the LC/LX globally.
