In a good market a 37 Dodge would maybe be worth that kind of money if it was either completely stock with extremely low miles and flawless throughout OR if the car had undergone a nut and bolt restoration. In restorable shape (a project someone feels is worthwhile to take on) and this market you may be lucky to fetch 5K.

Basically it depends on whether it's a two door or four door, original restoration, street rod, or for that matter a rat rod. If its an original you have to consider the cost for the resto and if you are performing the work or having it done professionally. Typically originals in this year and make are valued in the 25K to 30K range.
