I was told by the receiver of revenue to write the value off of my Suzuki Carry Van as it was worth less than £1000.00. But I would have to pay tax on the value I sold it for.
I would presume the same thing would happen in this instance. Each vehicle would be treated as a seperate case.
Not sure about the current truck status, but a while back a 2 door pickup, a 2 door pickup with a small space behind the rear seats (Kingcab) and a van were all treated as commercial vehicles. A 4 door pickup was once treated as a commercial vehicle but that changed to car status with different tax implications.
