I bought a 2010 with 10k miles higher over another low miles pre-lci.
If one goes by realoem the s85 never got the newer lead free bearings. So no surprise there. But are you sure you don't have 2 drain plugs? If so your engine was likely swapped at some point.My 2010 which is an 09/2009 build had 088/089 bearings when I did the rod bearings. Also don't remember seeing the second drain bolt.
Just to put it out there, since you are contemplating a 09 or 10.08 and 09 have the same radio and screen. Only difference is 09 has the newer idrive controller.
