It will need done.
But font let it put you off the car mechanically.
A fellow enthusiast friend has just traded his 05 GTI with 80k on it. He never had the belt changed in that time and the car never missed a beat! Yeah the service book says 120,000km for it to be changed I think, so it will need done. But if the car has been regularly serviced and well looked after. It should be fine.
My 06 has 43k on it and I haven't changed the belt yet. As my vw dealer said it didn't really need done until 6 years or 120,000km. But to be honest I will probably get mine done in the next 6 months.
