as far as #1, the people who have been contact by SmartUSA are residing in the USA, that is the only fact.
#2 should probably proceed with the various dealers by the end of the year
#3 - Smart has already indicated that an additional deposit may be required when the formal order is placed (its in the reservation fine print somewhere)
#4 - I'm sure the $99 deposit will be applied to the purchase price
#5 - also in the fine print, upon being contacted by the dealer, you'll have 30days to place your order. I would assume the usual 3-day right of rescission opt out will occur when you sign the actual order contract (I think that's law )
#6 all in due time!
