Yeah, I saw the P1,P2,P3 stuff on the tick sheet as posted above but it doesn't seem 350Z specific as some of the things on there clearly don't apply to our cars (e.g. Cambelt).
So it's hard to know what they should and shouldn't have done! I can say for definite though that not all the boxes in the P3 section have been ticked, e.g. spark plugs.
