Buying a high mileage superb

Hi all,

Looking at purchasing a 2010 superb 1.9tdi 105. Elegance model. 

Looks to have all the bells and whistles.

Mileage is 430,000km.

Was told a timing belt was fitted at 420km , had a new clutch, fuel pump and fuel filter.

Before I go have a look at it, what should I be looking out for on these? 

Any advice Appreciated. Thanks.
