What matters is that the world doesn't need yet another Golf with a different badge.
We already have:
Golf Passat Octavia Superb Toledo Leon A3 TT
I really don't think there's room for any more.
Fiat give their subsidiaries more scope for individuality than VW do, so I'd prefer to see them come under the control of Fiat and start producing more individual products, rather than them churning out just another VW.
(And I say this as someone who is a fan of both Fiat and VW)
