Not sure I understand the prices quoted in the Kodiaq forums post as they seem to differ from Citygates own website prices which as has been said do not mention any exclusions for particular models. Isn't the thing to do to raise this with Skoda UK as a complaint so I hope the author did that.
Before I looked into it, I thought,"Hello Marshalls up to their tricks again!"
I have suggested to the OP that he reports them to Skoda. But there have been no further 'looks' at the thread since my last.
TG for Meadens is all I can say.
