You are back to the same problem, you are buying a 5 year old car for a couple of grand less than you can buy a 2 year old car. Search on autotrader under A4, then put cabriolet in the special word section and you will see loads. Start at 'up to 2 years old' and make a short list, then add 'up to 3 years old' and add some more. Then call round and say you are ready to buy and offer them £2k less, and see what they say. You will get into a 2005 cab for your budget if you ring round.
