Yeah he's good. I bought some crystal smoked rears for my mk2 and he sent out mk3 ones instead by accident - I ordered on Saturday and they were here from Germany Wednesday morning. I told him of the mistake and he sent the right ones out and they were here by the following Tuesday.
We agreed that when a seller in the Uk wanted the mk3 ones I'd recieved then I'd send them on, with him paying me the postage to do so - as yet it hasn't happened, but I can say Yana is a great bloke (assuming he is a bloke!) to deal with.
