Not sure your indi price is that cheap if you need to supply all parts.
I would do jobs like microfilter and airfilter yourself, buy from ECP and fit in mins.
I recently had my third oil service at dealer, 4 yrs + oil service was £139, also got them to do the fuel filter which was £78 fitted. The rest I will do myself.
Vehicle check is a bit of a waste of time, if you look around your tyres, suspension etc you will already have done most of what the dealer do. Simple to reset the service schedule for this item if you do it yourself.
