Fairly expensive I'd say but then you are going to the stealers.
I just paid around £450 for P3, sparks, brake fluid, diff oil, gear box oil. P2/P3's don't include sparks, brake fluid, gear/diff oil.
If you know a good independent then take it there and save a couple of hundred quid.......if your feeling flush and want a Nissan stamp (For what its worth) then take it to the stealers.
