I would insist on a new wheel as well. If you are parting with that much cash for the car the least they can do is be professional about it and order a new wheel. I was build week 36 as well and my car is still in transit, only built last week so you are lucky to get yours now anyway. Oh how I envy you. Don't accept the fobbing off he is giving you with the demo wheel, insist on a new one.
