I've been curious about the seat adjustment too. I'm only 6 feet as well, but have brush my hair on occasion. Its kind of a problem since I've hit my head on the roof when driving over bumps and fast corners. I have a 500E. I once saw a dealer salesman reach into the seat bottom area and do something to make the seat go a little lower for a really tall person but didn't catch it. I know there is something in there. What do all these basketball players do?
