Leaks tend to develop at gasket areas, the water pump costs a fortune. That's almost certain to happen as the car ages.
There are some issues with onboard electronic depending on MY (airbag, window regulators, door locks), albeit these are "common" issues, they remain rare.
Its not too bad really, but you have to provision for some "maintenance/repair" money every year.
