My 18 has been great. It was one of the earliest ones built (February 2018) and has had a couple issues (cam phasers and a transmission problem), but they've all been sorted and I've been pleased in 4 years of ownership. I think most of the 18s floating around have had all the kinks worked out by now. And based on the sentiment of this forum, perhaps you can get them for a discount over their newer brethren.
Remember the 18s have a few features that were dropped from later MYs. I'm specifically thinking of a CD player, but I think they also lack the seatbelt airbags (which some folks don't like as they don't always play nice with carseats) and a couple other things I can't think of off the top of my head.
