Each auto maker has a signature look. Branding is done with styling cues that carry from small sports cars up to SUVs.
The Tesla Roadster is a first car from a new company. I wonder what signature visual cues will get carried to the "white star" from the Roadster. Tail lights, vents, headlights, or anything at all.
I would hope that the sedan is past the "red and geren sticker" part of developement process.
