67k Service Interval Cost estimate

[AggregateDemand]

Hey Y'all-
I live in the DC area and was wondering if anyone had an idea of the costs of the 67k service interval. Just the cost of the services involved with it and not any other gremlins that my be discovered.
Thanks,
James

I didn't know there was an interval at that random mileage....what does it entail?

....and how the heck do you only have 67k on your LR3?
