Thanks for the responses guys,
I think I best look at the paper work, but in short my plan is.
Buy stuff from Alex, Oil + filters etc
Take it to self service garage, basically you hire out a lift and tools.
Do the service myself.
Get the service booked stamped by the garage, they check over what you have done to make sure that your not saying you have done more work than you have. I would have thought they would be VAT registered.
If I do the above it will save me abit of money and I know it will be done properly.
The car I have got is a 2008 which is covered by an extended warranty.
