How do I journal the donation of a vehicle?

[wellspring]

I need some guidance as to how I should record a non-cash contribution (vehicle) donated in July. The church recognized the contribution with IRS form 1098-C and a letter sent to the donor that acknowledged the contribution but did not assign the value as per IRS. In August the church sold the vehicle.

1) How do I assign a cash value to record the original non-cash contribution
2) Would the journal entry would be as listed below but I wanted advice before I book the entry for July & August.

July
Debit - Asset Account (I think I will need to create an account for Donated Non-Cash Items) Do I use the dollar amount for which the vehicle was sold?
Credit - Contribution Income Account (create a new account named "Donated Non-Cash Items")

August
Debit - Cash Account (sale of the donated vehicle)
Credit - Asset Account

Any advice would be greatly appreciated!
