Just when I finally decide that the X5 is going to be my future car, I get an offer from Mercedes-Benz Credit that shaves $8500 off my lease buyout to $22,000. So now my head is spinning. Do I stay the course and lease a $65,000 X5 for $900+/- per month or to I by my E500 with 49,000 miles on it for $22,000? I assume I can negotiate that number too.

What to do?
