Not sure if it deflates the value of the car, but the 964 never sounded better. I can put the top down and still hear the music on the highway. The biggest down side, so far is the loss of some storage space to put the amp in. There wasn't much there to begin with, bummer.
Well, I'm thinking about going to a 996 cab in 2 or 3 years. I understand they have automatic roll bars that pop up in an emergency. Anyone ever been involved in a situation where it fired?
