51,000 miles on a 2001 HD and 82,000 on a 2004 Tahoe Z71. Bought both new. The wife racked up most of the miles on the Tahoe on her 60 + mile a day commute until we got her a G6 GTP, which now has 40,000 on it. The good news is she just changed jobs so now she has a 12 mile commute. Time to off the G6 for a G8!
