A seller's warranty is between the purchaser and the seller (retailer / shop / etc.) It does not apply to subsequent purchasers.
A manufacturer's guarantee may be transferrable to subsequent purchasers, but that is at the discretion of the manufacturer (e.g. the balance of a three year manufacturer's warranty on a car may transfer providing certain criteria regarding servicing and maintenance have been met by the original purchaser).
it does under sogsos 1980? Or is it the manufacturers warranty that extends. See http://www.consumerconnect.ie/eng/Get_Your_Rights/Shopping/Guarantees_/?tabParam=fullversion "A guarantee from the manufacturer gives you additional protection and supplements your consumer rights. The guarantee usually applies to anyone who owns the goods during the lifetime of the guarantee."
