Rolled back odometer anyone?
The original speedometer in my 65 Barracuda broke after it had turned over twice and read 50,000 miles. I.e., at 250,000 miles. Drove it without a functioning speedometer for a while, then replaced the original with a 150mph speedo out of a Duster 340. Have turned that one over, too, now reads just under 50K. I estimate the total miles on the car is around 350K. Here in Florida, you just mark the papers as speedometer does not read actual miles and you're OK.
