How often do you change your coolant?

I'm going to change mine after two years, is this over the top considering the Toyota (red) is meant to be long life?

I recently asked my local Toyota spares man and he said you should now use pink, not red. Pink is what they are using for replacement although red is still available. 120s all have pink in them.

Pink coolant = 100k miles (Bloody expensive)
Red coolant = 70k (IIRC)
