Wouldn't trust some car dealers any further than I could throw them. It's a regular occurence to get a job list as long as yer arm when a car has gone in for attention.
They look at you as if you are some kind of loon when you decline their kind offer to fix all yer car's faults, or are crazy enough to tell em that you are more than capable of undoing a few bolts to fit yer own discs or that you are quite happy to take the car away with its worn out sliding spline sproggle gromits
I'd guess main dealer rates are around £100 and hour for Volvo if you include the VAT.
I've not see a power steering pump itself leak, more often than not its the pipes that have rotted or fractured.
The other way of looking at it though is that you should have year of trouble free motoring, some cars lose £1500 or more a month in depreciation
