Popped back again today to pick up some cam cover o-rings, for when the lifters are changed.
Overheard another service bill.....
1 x oil filter
5L of semi-synth oil
1 x oil filter gasket
1 x fuel filter
1.5 Hours labour charge for the above.
1 x batetery for key fob
Total: £283 
Really puts me off new cars, That would be what on the 3.2 if I did it all myself. £25? 
£8 oil, £4 filter. Not sure what fuel filers are these days on TC.
You are not comparing like for like are you? You are comparing dealer rates with TC prices and free labour(ie you). Start paying non TC prices for oil etc and the difference will reduce. Then work out what your time costs are and the gap decreases. Then make an attempt to shop around and find a dealership that offers reasonable service packages and the difference then becomes negligible.
My local dealership did a basic oil/filter change with a general check over for £69 all inclusive, which was very reasonable.
Still at least 3 times what I would have paid. 
Depends on what you value your time at. If your time spent = £0, then maybe you are correct.
Not so in my case. So £69 was a bargain for me!
