1) Interior is all kinds of colors right now. It will eventually be grey seats on black. Original interior was white and it is getting replaced piece by piece. Exterior I haven't decided for sure but I am leaning towards orange with a $50 rustoleum paint job. I do agree with orange being domain of Mopars and Judges, but with a $50 paint job you don't have infinite choices. A yellow or a candy red are options, but I couldn't find any in the super cheap stuff.
2) Seats aren't heated, but I don't think it would change installation too much. I have 3 wires on my harness for the seats, and only used 2. There were 2 like 16 gauge wires and one like 20+ gauge. I have no idea what the 20 gauge is for, so its just sitting off on the side now. With heated seats I assume the wiring would be the same or just doubled.
3) For wheels, I haven't decided yet. They will be to complement the rest of the car, so I figure they should be last.
