I put 8000+ miles on my 2016 M3W. When running well, it is the most enjoyable driving/riding experience I have had. I am no one’s idea of a mechanic, but I would say that if you don’t have a dealer or a speed shop/other reliable mechanic to help you, you will have some frustrating days. Even with my limited skills, I did plenty on mine. Some musts include changing the stock fuel pump (Walbro; great instructions here helped me do it), upgrading the headlamps, keeping an eye on every screw that you can reach, and replacing the battery and keeping it charged. Keep an eye on the oil reservoir gasket too. But other things like changing the rear tire, keeping belt tension correct, etc require some help if you don’t have the ability to do these tasks. It’s great fun to own, but definitely labor-intensive to gain the knowledge and keep them happily motoring.
