Too many miles?

[DTMB]

How many miles are too many miles on a XB9(S) or (SX)? I'm looking to pick one up over the winter and wondering whats too many.

I'm sure I'll get responses along the lines of "they can run forever if properly maintained" but that doesnt help me much. Just looking for a ballpark.

Thanks,
Mark

75k without problems if maintained.
