A slow response from customer care center (as I asked what the latest version is of the computer firmware and what is improved into the navigation maps) since I already had the firmware on my '17 updated from 59.00.330 to 59.00.504 last week Friday, March 30th as the dealer service manager says...
kinda having a late buyer's remorse here.
the top right motor mount is 3x the price of 2.0, the alternator is 2.5x the price of 2.0.
I hope that's not the case with the 2015s...
