You can not transfer the apple care from one machine to another. However, the new owner will enjoy the benefit of your buying it when you purchased your machine. It will also be good to sell it advertising the remaining time of apple care on the machine.
Good luck selling it. I just got the 13" mac pro and will be selling my air with SSD on ebay. May even consider craigslist, but haven't tried that yet.
Thanks for that. I just spoke to an apple rep on the chat (I'm in the UK) and apparently all new Macbooks purchased with the higher education discount come with a 3 year limited parts and labour warranty that is the same as the apple care. Is anybody else aware of this and do you think this will be the same as the apple care itself? If so, I'm happy to sell my current macbook with the applecare and just buy a new one and save on the cost?!
