I like the new 7. I had a 2012 750Li and loved it, I was hoping they didn't get too creative with the exterior. The new design is conservative, driver focused, and lighter. I'm sure it's much lighter and nimble compared to the S-Class. The shape is more masculine conspired to Merc.
The new interior is amazing. Might have to trade in the 6GC for a 750 M-Sport.
