picked mine up new with only 5 miles on the clock, as of today sitting at 16,3XX. break in was done in less than 1 week, but thats only due to having to drive family members around for a wedding that was going on at the time that was about 70 miles from where i live, still stuck to break in procedure, but boy it's hard to resist driving my Z on the weekends. I have been taking it easy though the last few months so hopefully won't rack up to many more miles this year
