Hi-I am thinking of buying a Ghibli S (UK) registered in December 2016 that has the updated infotainment system with 8.4-inch touchscreen display. Was this upgrade done at the same time as the switch to electric steering and engine tweak up to 424 bhp, or were these improvements in 2017? Finding it hard to see exactly what upgrades were done when. Thanks to anyone who knows for sure! Best wishes
