i noticed on the internet in australia that 6.9s are selling if in reasonably good condition approximately 20,000 dollars. I think the reason being that only just over 7000 were produced worldwide. If you can buy one in good condition which is mechanically sound they are tyre shredding monsters with huge torque. Obviously they were not built for good fuel economy. If the pneumatic suspension is in good working order the ride quality of this vehicle is probably the best in the world. The 6.9 is a exceptional vehicle and probably becoming quite scarce by now and thats why the value of this vehicle is climbing.
