I feel like if I can find a 2010 with less than 30k miles for around $60k, I'll be doing OK, but will there be another big round of price drops on the X5M? Will there be a glut soon with 24 month lease returns?

Seems like 30-40k has been lopped off the top on these. Plenty of them on the market for optimistic prices, but they sit and sit. Are we soon at a place where they trade in the mid-40's like the E60 M5 and virtually worthless without warranty?

Help me understand so I can plot a strategy.
