I knew I wanted the tech package when I was buying the car. So while browsing numerous online ads, I was able to quickly establish if the car had all the features I wanted just by seeing the ICC sensor in the front bumper. Then it was on to an interior shot to see if the leather was black and to verify the presence of a snow switch.
Found what I wanted in a matter of three weeks. Called up the dealer for a walk around and was on a plane to pick her up in less than two days.
