I live in London, so i think it's safe to assume they haven't dealt with Nissan in your area.

they had to deal with Nissan higher up than consumer affairs. and it's easier for a company to purchase something like a rolling chassis than it is for an individual.

your best bet is to call around other dealers and see if they can help. if that doesn't work, you'll just have to look for a used one and strip the interior.

why do you want just a rolling chassis?
