Wow a 6 cyl one.. we dont see many of those. Im not sure on the weight of the 6cyl ones. :-S
Welcome mate. Have you got some photos of the shell. If it is "full of rust" I wouldnt imagine it would be worth an excessive amount especially given its a 6 banger. I would weigh up the value being the sum of the GTS parts that are on the vehicle and their condition.
A 6 cyl can be good in some ways as this can free up what you wish to do with it. When they are origional L31 models the pressure is to restore them as per origional. This would be ripe for a transplant with later running gear and make a pleasant driver. Cotillion White and Slate Black trim is a desirable colour combination.
