I've received different statements from different dealerships. One says yes the GLE400 2017-2018 (build starts this month July) will have the 9G- Tronic and the other dealership says no, the standard 7G-Tronic will stay the same. Do you know where I can find the correct answer? I wanna order the GLE400 but only if it has the 9G-Tronic. Your thoughts?
