I've been exploring building my own car from scrap. This wsj sort of motivated me (1). The ideal would be no electronics at all. An issue I have with new cars are monitors, I hate them they are distracting. My eyes are pretty sensitive to computer screens etc. Maybe, I'd settle for just a radio. "Maybe" because you then get looking at a cd player then all the sudden you want the further desire to control what you listen to and before you know it you are talking about mp3/digital and more computerization/softwaring of the car.
The first question is... what do I want? The second is the more complicated issue of getting it done. However it has always been a dream of mine since being a kid and watching the Home Improvement sitcom in the 90s.
