I tried to get my car through a novated lease... answer was NO. Basically because it's a grey import that is not on their list of supported cars. Also, the car is "too old" the be considered for their terms and conditions (they need a relatively new car so that they can still make money when they sell it off)
Besides, since these types of arrangements include all on-road costs (insurance, fuel, and rego etc.) I don't think they would bother with a car that they have very little return on.
