What should we look for when buying a Toyota Prius hybrid?

My wife needs to replace her 2002 Toyota Yaris, partly due to its age and partly as she needs a larger car due to growing children and sports bags, etc. I would like her to have a Ford Focus, but her heart is set on a Toyota Prius. We have a maximum of £7500 to spend, plus whatever we can realise for the Yaris. Never having purchased a hybrid secondhand before what should we look out for? How can I tell if the batteries are any good? Would it be foolish to buy one of that age privately, or for that matter at all?

A used Prius can be a very good buy because they are ultra reliable and the hybrid drive system and battery has a long warranty. Best to eliminate potential worries by buying a p/x from a Toyota dealer.
