A good portion of the value will be attributed to the type and condition of the wheels. Factory steel, lugs, factory rubber, cutdown rubber, condition of rubber, etc, will have a big impact on the value. As a complete non runner, your value would be in the $700 to $1000 range. Factory steel would raise those numbers a little, especially with full lugs.
If you can find actual sale prices, they can be all over the board, and may not include many of the details that impacted the value of that particular sale, leaving you still without a good basis.
Values can vary by region, but this model should be pretty consistent across the nation.
