Always a sweet spot. I would make sure 12000 mile big service & valve check has been done. I am on my fifth V4. all brilliant. But to my mind the 2016 factory has been the sweetest. Not as many toys on it, but in my opinion the best fuelling of any year I have had. Currently running a 2019. 27000 miles on it. I've had it from new and very few minor niggles.
