Just rolled 220k on the Celeb today. I think the 6k winter wagon has about 255k. My Trans Sport van has about 285k. My old 6k wagon has 255k.
True my Celeb and 6k winter wagon don't work as hard since hypermiling. But I've had all my cars long before hypermiling and they have worked hard. I never really went over the speed limit much but I used to drive zippier than I do now. My van hauls pulls my wood trailer and my travel trailer. My old 6k wagon used to pull the wood trailer, I used to take it off roading, and since 2005 it has remained at 255k while it plows my driveway every winter using a powered V plow I built for it. All my vehicles have GM V6s and 4 speed automatics and it's like the drivetrains are built like tanks. When the wheels are ready to fall off I'll go to Swain's junkyard and get some more bearings and put the wheels back on.
