Maybe VW will do an Anni R in the next year or two with some trick front suspension settings to give it CS handling and R traction. Stranger things have happened.
The question is what could they do? I'm sure it'd be for the 25th Anniversary of it (It did start at the mk4 didn't it?) Seeing how the golf now has the aluminium subframe of the Audi A3 and is already pushing too much up on the S3.
Of realistic things I'd expect from one it would be a mild hybrid drivetrain (at a push) with bigger lighter brakes with a few graphics and a mild bodykit.
One last hurrah of a VR6 would be nice though, even if it was still at 320bhp.
