Steve, one additional "possible" consideration. When I was juggling the decision between the two, a salesman brought up the windshield. According to him, the Eyesight uses a special windshield you'd have to purchase from a dealer should you get a crack or break. He made it sound like a rather large expense versus going to Safe-lite or the like for an aftermarket glass? It sounded reasonable? I'm on my 3rd windshield for my Suburban in 5 years, so it worried me if its true.
