Servicing costs - are you serious?

[ftypical]

Just been looking at the menu servicing of my local dealership and noted a remarkable disparity in the price of Inspection I between an E46 330ci and M3. They're doing exactly the same things, but while there is a difference in parts prices, it is no where near the all up price difference which is mind boggling.

Consider: 330ci - £249. M3 - £669

Inspection II is worse.

But then, they charge £63 pounds to change the micro filter...

Currently £35 for 5 litres from ECP. Halfords still charge £16 for a litre mind...
