I think its hysterical that NADA actually DEDUCTS from your cars value for NOT having a sunroof, but yet when you go to buy a used e30, e36, e46, they sell for a couple thousand more without the sunroof......Its logical to all of us why that is, who wants to build or buy a car thats at an immediate weight disadvantage, especially if your going to track it.....and like pretty much everyone said, conversions are expensive and never as good as stock.....Sunroofs and convertibles are for chicks anyway.....or guys with pet birds
