mileage on your car

Wish I knew. The speedo shows 29,000 but I'm wondering how many times it rolled? We believe the wagon was used for rural paper deliveries in west Texas ( a lot of ground to cover) so it could be 429,000 for all we know. Pedals show pretty good wear and the steering wheel is worn to the black rim. My guess is at least 229,000.

The 383 Dart has 57,000 original miles.
