My Duster is going to get all of the miles. My plan is to pull my Fury "off line" for some much needed modifications and bodywork which should take me 1 - 2 years (no powertrain work though, that's rock solid). On the mileage the manufacturers intended, I don't know.... Every Duster I've had I have put no less than 100,000 plus miles on them. My family put at least 80 miles a day on a 69 New Yorker for 10 years(!) with very little in the way of wrenching outside of normal wear and tear. We got lots of land to cover down here in Texas :-D. I think if you do real maintenance on them they'll give ya lots of trouble free miles... I understand there is a tradeoff in everything but I'm still checking every angle.
