I've actually been looking for adaptive drive ("AD") on a used 2010/2011 also... experience has shown that it's almost never listed in the options, but you'll see that sport button next to the shifter when you look at the pictures online. Amazing that a dealer has a car with a $3,500 option and they don't even bother to list it. Sun Motors in central PA is a prime example, they have several 2011's in their used section with AD and it's not even listed in the options.
