As for the ABS, don't waste the money if you truly like to drive. I've had it before, and unless ice is a common problem where you live, it takes a lot away from being able to "play" with the car. It seemed to kick in at very inappropriate times for me, like when I wanted to throw it into a turn hard and hit the brakes late going in. (May have been crappy tires too, but it was a company car)
As for the Moonroof, I don't know about the tilt thing, but I really wish I had one. Someone on here got one off the floor that way, and I'm jealous. It's definitely a nice option, and would make your MP3 even more rare.
Just my 2 cents..
