Rudy, just a word of warning. If any of your friends ride in the back seat,(and decide to use the rear seat adjuster) tell them to be very careful.
I tried one out at a New Car Show when they first came out, and it laid my finger wide open, and I started bleeding like a stuck pig (no pun intended). Needless to say the model standing next to the display wasn't very happy with me bleeding all over the place, and I actually had to go to the shows 1st aid station to get it taken care of.
