2005, 156 Timing Belt Replacement

[saratoga]

My 156 is approaching it's 60k service and I am being told by the dealer my timing belt needs replacing @ 60k however the service book advises checking it @ 60k and replacement @ 120k. 
Half the distance travelled has been on freeway at above 100kph and 40k of that in the last 12 mths so I would not have expected a lot of wear. 
Does anyone have a difinitive answer on when it should be replaced??
