Thank you both for your reply. That deal fell through so I went with a 2018 SL with 5K miles. Going with an extended warranty to 75K miles but after what I've been reading, I don't even know if that is enough. But, I guess I'll probably get rid of it before that anyway. Seems like an extended warranty on these is a must?Also, some 2017 Platinum options are now standard on the 2019 Muranos. Things like LED headlights and 20" wheels, and some of the safety stuff from the Technology Package too I believe. Plus, if it's not a 2017.5, it will be missing Apple Carplay. The 2019 model adds Android Auto.
I agree, the extra couple of years on the warranty alone is worth going with the 2019. I also assume the 2019 is new with no miles?
