N62s eat the valve stem seals.
As I said earlier, the 4.6is was the worst X5 out there reliability wise. Unique engine, unique transmission, all highly stressed versions of pretty unreliable base components. The ZF6 is a great transmission, and the N62 is much better than the M62.
And don't forget that the N62 4.4i has 315hp. You may prefer a lower specced 4.4i with less to go wrong and a little less stressed parts vs. the 4.8is.
