Like the LR2 - which always sold like gangbusters over in the Europe but mostly sat collecting dust in US showrooms - I think the Evoque has a more limited appeal here in North America, with its smallish dimensions and 4-cylinder engine, and despite its in-your-face, modern styling that without a doubt brought in huge sales numbers in the beginning to the metrosexual types (both males and females) I normally see behind the wheel. Even Land Rover must have known those numbers were not going to be sustainable in the longer run.
In fashionista LA / OC they still seem to be everywhere, definitely easier to spot than the LR4 and at least as popular as its less flashy small-SUV competitors, but I am sure sales are tapering off around here as well. The Evoque will continue to do a lot better in countries where fuel is expensive, such as Europe / UK. But I'm afraid its edgy styling is a double edged sword that may already look dated to our local trend-setters, and when they move on to something newer and more exciting (you'd think Tesla was the best selling car in the world if you drove around L.A. today), sales normally fall off a cliff.
