Cobos, I understand what you are saying.
I made this argument to Tesla via email.
Think of all the deposit money as an interest free loan to Tesla Motors.
Let's estimate that the deposit for the sedan is about $25,000.
Before this recent crisis, I think Tesla Motors might have been able to get 3,000 pre-orders with deposits. With the total cost of the Sedan at around $57,000 that makes it much more affordable to a wider customer base.
3,000 deposits X $25,000 = $75 million
Let's say that Tesla Motors has to pay about 10% on money.
That $75 million in the bank as an interest free loan is worth about $7.5 million per year to Tesla Motors. The Sedan is esimated for 2011 (which really means 2012 with delays), so Tesla could have saved at least over $22 million in interest with those deposits.
How many preorders will Tesla Motors get now for the sedan model? I have no idea, but I am sure the number is lower than it was about a week ago.
