Hmm, I read it to imply that we could be asked to put down an unspecified "Additional Fee". If one cancels after putting down this Additional Fee, then you get back "all reservation fees paid less a $10,000 cancellation charge". That language suggests that the Additional Fee will be no less than $5,000 and quite possibly more. It wouldn't surprise me to learn that we need to top up the reservation fee to 40% or 50% of the estimated purchase price (which would be in line with the Signature deposits).So, for P reservations atleast, it appears that we may have to front another $5,000 when asked to configure and order the Model S and, if you were to backout after that, you'd stand to lose all $10,000.
