Very logical - makes good sense! But in reality its unlikely that would have happened... 2 previous owners, etc etc. Probably all just garage services before the customer takes delivery!
Only thing to do then is go for the big one P3 and be sure.
As I have posted before, there is absolutely no difference between a P2 and a P3 apart from the price!
The only difference in the service schedule (page 19 of your service book) is "replace" the LSD gear oil instead of "inspect", but that doesn't apply to us cos we have the viscous coupling type.
It's a rip off from Nissan - there is no difference in the services. Just get a P2 done (nobody ever needs to pay for a P3).
Maybe so but does'nt look good on the service history IMO
