Yes, simplicity can be good sometimes, but not always. For example; what if you pull up next to someone and need to roll down your pass. side window. This means you have to reach clear over the other seat just to do it. Same thing when needing to unlock the pass side door for someone. Also, I know on my car, and heard of others, who´s windows don´t roll up well with the normal crank. Finally fuel injection tops carberators because they offer more efficiency and have better reliablity. Thats just my two cents.
I do have a question though, can you convert crank windows over to power windows fairly easily or is it a pain in the butt?
