Much as the others say really.
I wanted a CVT, didn't want/like the diamond cut bigger wheels, I actually like the alloys on the 2018 SE, the folding mirrors and a few of the other SE spec items and that sort of decided it for me. Plus I wanted the "polished metal" (aka shiny grey) colour and fairly low miles, and the idea of being able to fit a spacesaver spare for when(if) I get to do some continental touring meant the later year models weren't ideal.
Having a narrow spec wish-list limits the choice but makes the decision easier when you do find a good one.
