Now that the Tesla model S is finally coming to HK (at least, prices are released and orders being finalised), the time has come to decide on specs. I am planning to go with silver metallic paint, light coloured leather upholstery and no sun roof - all three decisions mainly as I think it will decrease the passive temperature rise when the car is outside in the sun. I would like to know from present owners how you think the sunroof in particular, is affecting the cabin temperature? I think the sunroof is nice, but if it is going to make my Tesla a green house, then I'm not having that option. In any case, I do like silver metallic for paint, and it's normally easier to maintain and sell. If I could have had a chromed-up mirror-paint Tesla, I'd probably even gotten that! If it wasn't for the heat absorption, I'd probably gone with the standard upholstery, the leather is mainly as it's the only way to get a bright interior.
