is it a manual or auto ? If its an Automatic find out if its the second one . They usually last 250 odd kmi, my wifes one is slipping and about to go.
The engine itself is bulletproof. 300+ kmi is easy.
Water pump - check that the aux pump works, heat is a bad thing for this block/head combo. As long as the cooling system works and it has no problem glowing and starting buy it.
