What's the difference between the two?

VW offered 3 trim levels for the 1st Edition

1st Edition Max (top spec)
1st Edition Plus (middle spec)
1st Edition (lowest spec)

There is very little mention of this in theUK though as we only get the middle (Plus) spec.

As above, you only get the 'Plus' in the UK. It doesn't have wireless phone charging that the 'series' models have, like the Life, Family etc.
You don't get the Head up display (HUD) on the UK 1.ST either.

Or the lane guidance, traffic light recognition etc.
