Chevy HHR Network - Highest mileage you have ever had on a vehicle?

1982 Volvo 245DL station wagon 2.1L 4 cyl ; 305,000. 4 spd manual with OD. It was wife's kid hauler and served us well when our family was young.
1988 Volvo 760T 2.3L 4 cyl turbo, auto, 270,000 - my favorite highway car. Gave it to my older daughter to drive and she beat the crap out of it
1994 Volvo 850 Base Wagon 2.5L 5 cyl auto; 250,000 - One of the most comfortable cars I've ever owned; got rid of it because I didn't want to spend the money for a new cat and the rest of what it might of needed to pass smog.
1997 Ford Aerostar XLT 4.0L V6 auto; 220,000 - bought new to replace the Volvo station wagon; new interior, parked a while back with a head gasket issue; hesitant to let it go as I put so much money into restoring the inside
1989 Ford Bronco II 4WD, 2.9L 5 spd; 250,000 - another vehicle trashed by my older daughter; just rebuilt the 5 spd trans; need to get it running again as it has been sitting too long; want to hold onto it as they are now going up in value
1993 Saab 900 Turbo Convertible 2.0L 4 cyl turbo; 256,000, still runs fantastic, put new top and new interior, needs work to pass CA smog, body needs refreshing, debating whether to hold onto it as my personal Saab mechanic passed away last year; probably the most difficult car I have ever owned to work on
2008 HHR SS, Silver 170,000, Auto trans; completely stock except for Performance driver's seat, Wife's daily driver and my favorite ride also; bought from local dealer as a CPO w/70k miles 6 years ago; Uses 1 qt. oil every 3000 miles; I have new LCAs and OEM struts to install when I can find the time. After we sorted out the issues at the dealer (ignition switch, sunroof issue, powertrain control module, etc.) under extended warranty it has been a very reliable car. We still get compliments from strangers wherever we go with it!
