I don't want to burst anyone's bubble, but there is no true Factory Extended Warranty available for the smart (i.e. no product that truly extends the terms of the existing 2/24 warranty).
The product you purchased is a smart branded third party warranty from Automotive Warranty Services. It has the smart logo on the forms, but if you read the contract, it is administered by AWS, subject to all their standard conditions and exclusions. As such it is no different than any other third party extended warranty that you could purchase for your smart, now or in the future. In fact, it is not a particularly good product - it has a $100 deductable (other vendors let you choose a lower or zero deductible if you prefer), and it covers only breakage (others include wear and tear).
There has been plenty of discussion about this warranty on other threads - just do a search on "warranty". An extended warranty may make sense for some smart owners, but I recommend shopping around on the net to find and compare the different products that are available. There is absolutely nothing unique or special about the smart branded warranty you can buy at the smart dealership.
