The price was the main factor, it was cheaper than anywhere else I could find by over $5K even after I take into account delivery fees. It was also from a dealer so I didn't worry too much about buying a lemon. Took it in for a road worthy check and passed without problems so I managed to get my ACT plates today as well.
One thing I was surprised about was the window had a "Lexus Auto Alarm" sticker on it so I guess this means it's got an alarm. Wasn't advertised and I'm not sure if it's a standard item but I'm happy to have it either way.
