Ah okay, thanks! That's simple enough. And to your point, at some point an SA might contact to ask if you want to go ahead at which point you just explain you are waiting a little while to finish the registration process? Do you know what happens when you decide to go ahead and finish all your details? Are you still at the back of the line similar to if you had started a new order at that point in time or are you "ahead" in the process somehow? I suppose at the very least this should allow locking in the current price if prices do go up by a bit if tax-credits look likely?Place your order, and there are like 5 stages (delivery location, registration details, insurance details, payment, etc...). you won't get matched to a vehicle until almost all of them are completed (maybe even all of them, not sure about payment).
Just don't complete any of the details. Just submit your $100 deposit and then sit on the order. you'll get an order confirmation showing the pricing you locked in.
