I agree with Romio. Maybe <3k, <5k, <7.5k, <10K, <15k.
Too many of us have less than 10k miles. I just turned 6,000 miles.

FP, Why don't you also start one for how long you've owned your Crossfire, and that way we could get any average length of ownership as well as the average number on miles. It might be fun to see the outcome.
