How can I check a car's service history?

Can anyone give me guidance on obtaining the service history on a 2012 Mercedes-Benz B-Class 180 CDI?0 The basic info shown to me at the dealers is different to that obtained in a RAC search.
You're not being clear. All the RAC can do is interrogate the DVLA MoT databank for mileage information at MoTs, which is often misrecorded by the MoT inspector. It can also tell you if the car has been damaged and subject to an insurance claim. If Mercedes has recorded the service and warranty repair history of the car on its central databank then that it what you can call up from there.
