You don't need a 1987 van, anything before ~2007 should qualify. For example, I own a 2006 Honda. I made the mistake of leaving the windows open several years

You don't need a 1987 van, anything before ~2007 should qualify. For example, I own a 2006 Honda. I made the mistake of leaving the windows open several years ago before a massive downpour. As a result, virtually all of my onboard electrical systems no longer function (radio, interior dashboard lights, ect) but the actual function of the car (as far as driving is concerned) is unchanged. I shudder to think about what would happen to a "smart" car in a similar situation.
