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.

My questions are: 1) How exactly does a hybrid car work? 2) How is the electric part recharged and how far would the average car travel on one charge? 3) Would the driver in reality use the petrol part...
