I don't know, I even see this pre-order list as part of the ploy. So you show up when the car is there, and there is someone off the street willing to pay MSRP just waiting for you to back out. To me it is the same process as listing a house on the market low, but waiting for multiple offers (bidding war).
I went to check out a veloster back in Nov/Dev. They had 0 new, and one used with like a months worth of miles. Said a buyer tried the 5-speed but decided they wanted a auto. They were asking more for the used one than new MSRP. Now, they have 20 on the lots...
I think I'll sit it out for a few weeks/months or like others have said just work with Toyota. I don't get all the fuss about getting the first one or being on some list.
