Bought the missus's old corsa without a service book, and had a look on ebay for a new clean one. Couldnt believe how many were there all for sale as it really can be abused. That was a couple of years ago, and I read something after Googling it about ebay insisting they were looking heavily into it. Obviously did sod all then, so I doubt they would now. New/Copy ones are fine for people who want to put some sort of history on their car if it has none, but old ones coupled with a used set of clocks can really turn out to be someones nightmare, especially if they have not been checked out properly.
