Power sunroof and rear DVD entertainment hanging above from roof were options on every version. 06 has smooth leather seat bottom in the rear vs Alcantra suede in 07 and later.Thanks, that makes my 2006 SS a 3SS. Mine has the leather seats, digital controls, rear entertainment center, power sun roof, dual power seats and more. I am the second owner and it now has 134k miles on it. I drive it daily and have had very few problems with it. I had to replace the ignition switch and the rear wiper motor. I am a retired ASE Master Tech and maintain it almost to a fault. It looks great and runs great and has never let me down.
