Worst of show so far? Definitely the 2017 SL63.
Best is perhaps the Fiat 124 Spider, or the new Mazda CX-9. Or the new Honda Civic Coupe!!! Just the humdrum EX trim shown so far, but it looks hot and wide and high-tech from all sides.
Also lovely to catch any glimpse of the 2017 Ford GT supercar, plus its kid bro the 2016 Focus RS in Nitrous Blue.
