The oldest known surviving product of Ford Motor Company, a 1903 Model A Rear Entry Tonneau, has had only five owners since it left the factory over a century ago. On October 11 an 12, one bidder will have the opportunity to become buyer number six as the car is again scheduled to cross the block at the RM Auction in Hershey, Pennsylvania.

We say again, as the car was sold by RM Auctions in 2007 for the impressive sum of $693,000. As Hemmings Daily explains, it was offered up again in 2010, at RM Auctions’ Monterey event, but bidding stalled at $325,000, well south of the $600,000 to $800,000 pre-auction estimate.

This time around, the estate of the current owner has attached a more realistic (or perhaps pessimistic) price to the car, with the pre-auction estimate set at between $300,000 and $500,000. Like fine art, vintage cars (even historically significant and well-documented ones) don’t always appreciate in value.

The Model A was one of three cars built in the first batch to come from Ford Motor Company’s Mack Avenue plant, and the other examples (serial numbers 9 and 11) are believed lost to history. Serial number 30, the car for sale, was purchased in July of 1903 for $850 by the McNary family, who owned the car for some 50 years.

If you think the time (and price) are right to add it to your own collection, head on over to the RM Auctions site for complete details on bidding at the Hershey event.
