What should I look for when buying an Aston Martin DB9?

Unfortunately there is no column like yours in Canada, so I am writing to you. I would like to buy a 2005 or 2006 Aston Martin DB9 convertible. What are the concerns I should look at before buying, and how should I care for it? It will be used about 5000 miles a year in good weather and kept in underground parking when not in use. It will be left for a few months at a time when we are out of the country. Are there any real reliability issues?
Sorry, we don't get much feedback about this level of car. All we do have is here: www.honestjohn.co.uk/carbycar/aston-martin/db9-200...d. Astons have always been very expensive to run.
