Audi A4 (B8) wing mirror - wanted

[jdragon]

It's starting to bug me that my drivers side wing mirror if different from the passengers side so I'm looking for a drivers side replacement to match the one in the attached photo.

 

I'm not sure why they are different - I remember the same thing with a new Polo my wife bought (drivers side being bigger) but the sales person said it was normal, and my wife wasn't bothered so we just accepted it.

 

Travelling isn't an issue but it would be great to know of a reliable online supplier or someone in my area :)
