I'm not currently driving a car yet over 100K, but I know of quite a few high mileage DD cars, I'll post them.. cool stuff
My friend had an 87 Carb'd Prelude. had 335,000 kms on it when I saw it last (a few months back) and ran relatively well.
Another friends' father had a 97 or so Starcraft Suburban, had over 400,000 kms on the odo, daily driven from London, Ontario to Toronto and back almost daily for a few years.. WOW!
yet another friends dad, had a 88 or so Volvo 740 with 485,000 kms on it.. something finally let go on it.. enough for them to park the car and eventually just sell it for a couple hundred bucks.. that thing was a trooper that's for sure!!
and last but not least, my best friend had a Sundance turbo as his first car.. bought it with 310,000 on it for $500.. drove a year without a single problem and then sold for $700, with over 340,000 kms on the odo
i'll see how far i can take mine.. heh
