Bookkeeping question re vehicle disposed

[AZ-Tax]

When a 100% business use vehicle that was placed in service 3 yrs ago, is disposed of in 2009, where in books, if at all, does the disposed vehicle appear?

[dsi]

Cash-debit
Accumulated depreciation - debit
Gain/Loss on disposal of asset - debit or credit
Vehicle - credit

The above assumes there aren't any notes payable on the vehicle, and you received cash when you sold it.

I did a search for the vehicle that was disposed of

by "memo" and nothing. I went to "other income/expenses" acct and nothing yet on the P&L under "other income/expenses" it list "gain on disposal of truck" but I have no clue what the sales price was.

Go to the source of the entry. Who made the entry and what is the detail of the entry?
