I have two of them. One in a 05 with 430k miles and a 06 with 407k miles. I was told the same thing as others, they will run 650-750k without issues. Seems to be a lot of International 8600's with low 400k miles for sale (that's what mine are) I don't know what their asking but $25,000 will buy one like mine. I thought that was a good price for something that new with those miles.
