Volkswizard has always been at the stronger end of the price spectrum, but that's because he is a proper dyed-in-the-wool VAG enthusiast and only buys and sells the best examples he can get.
TBH, a VW expert like him separating the wheat from the chaff isn't a service I would mind paying extra for, personally. My days of turning up to view cars advertised as mint, which were far from it, are over.
