Another vote here for original Mk7.
Not a fan of the new headlights or the bumper or the wheels. Also, I really do not like the new LED tails. Saw it in action on a couple of NAR 2018 GTIs last few days and they just look...terrible (especially the turn signal). Actually prefer the current incandescent ones to those 7.5 lower model LED tails.
And between the 7.5 higher model LED tails and the 7.0 LED tails, I like the original better overall - though I do think the light pattern of that 7.5 higher model LED is pretty cool. If they could combine the exterior look of 7.0 LED tails with LED pattern of 7.5, I would throw all my money at that
And I saw one of the 30 new colours available for the 2018 Golf R in person the other day - in a deep purple. Can't say I'm a big fan of that either... Certainly unique.
