I have been lurking and learning on this forum for quite some time, so thank you to everyone for your comments and insights. I have test driven the Model S twice, and today is the day I'm placing an order. Any and all comments and insights are welcome, particularly around extended warranty and service plans and whether paint coatings are a must. I'm planning for a Model S 90D in midnight silver metallic, panoramic roof, 19 inch wheels, smart air suspension, black next gen seats, autopilot, premium interior with black alcantara headliner, and carbon fiber trim.
