My first opinion (trying to see through the rather naff flat looking configurator images)...
1) Nicely updated interior/dash
2) Rear lights rather austere looking (hopefully better in the metal)
3) Grille surround very heavy looking to me (again hopefully better in the metal)
4) Full digi display clearly a cost option
5) Nice new aggressive front air-dam for M Sport... looks good
6) Crease running up into headlight notch on M Sport gives a really nice aggressive edge to car's appearance
