No real call for them, as above look how many breakers there are advertised on ebay. The mk3's are into DIY territory so i'd guess thats really hit the demand for mk2's. I like mine but look how dated they are compared to even a basic spec mk3 - its not even got cupholders!!
It wouldn't have put me off buying but i'm surprised at how quickly the mk2's have dropped off the radar now.
