I know of a 6.9 engine available in Sydney with 180,000 klm. It came out of a car with a comlpete maintenance record. The car was condemned for some poor structural welding work, so it was parted out. The engine and gearbox are both available. I think it would be about $1500 perhaps. I have actually seen the engine running before it was removed from the car, about a year ago.
The right rear door that is on my car currently, came off that car. The bonnet and bootlid were given to me from that car, and are available, too.
