nicholasa631 - I faced the same question in late October 2016. Money had no weight in my decision. I've owned an FXR, FLHT, and most recently a Dyna Super Glide Sport. I rode both the 2017 and 2016 Street Glide, and I bought the 2016. I have only 1300 miles on it so far, but I'm very happy with it. I mean no disrespect to any of the M8 fans, and I wish them no bad luck, but I haven't known a single first year power train, car or bike, that didn't have demons needing to be exorcised. My buddy bought a M8 Ultra Limited two weeks after I bought my bike. Right now it's sitting in the dealership (for the third time) due to a transmission leak that they cannot locate. HD is sending a new transmission case for them to swap in. I hope the M8 turns out to be rock solid and that my buddy's bike was just a one-off anomoly, but...
I'm sure you will love your 2016.
