I just drove my buddy's '06 Corvette, (balls-out awesome!) and he has a feature that I would love to have. When you get within 3 feet of the car, the door unlocks and the alarm disables. You just have the key in your pocket. Then you just push a button to start the car. When you get more than 3 feet away, the door automatically locks and the alarm is activated. Do any of you folks know if anyone is making this aftermarket? Thanks.
