Check the interior, engine bay and the general feel of the car. If it looks like it still shiney and new, chances are it has been well looked after. If the seats, dash, engine etc looks worn but it says 60 000 KMs on the odo... comon.
Be prepared to pay a few grand more for nicer examples, they are worth it.
A great way to overcome mechanical and maintenance problems is to service your car regularly, every 5000-7000 KMs. If you suspect such things like coolant and sprk plugs have not been changed prior, do it.
If you keep up this type of attitude then the only thing you really will need to pay for weekyl is petrol and annualy insurance and regestrations.
They are great, quick and reliable cars. Ive had mine for over a year and the only thign that went wrong was my right bushes popped and spat grease under my car. It cost $60 bucks to get two replacement ones, I replaced both at the same time... the labour was a bitch so I got my family mate mechanic to do it.
So yeah if you know how to do half the labour yourself or with a close friend or relative, your laughing.
