I have a 1994 Ranger, the odometer broke at 99,999 miles in 2001. I'm guessing it's close to 300K. I almost bough a 2011 Ranger a couple years ago, but put it off when they announced they'd be bringing it back.
Just replace the speed sensor and the odometer and speedometer will start working again. Part is real cheap and you can do the job in about 10 minutes.
If state ever go to a mileage fee, it's very easy to disconnect the speed sensor on a number of vehicles. No operating speed sensor = no miles on the odometer.
