I was also wondering about this conversion, It is a pain to have roll up windows but on the other hand motors go bad and cables get stretched and off track and sometimes power windows are a pain, plus in the winter they freeze. But it would be nice to have pw.
I definitely wanted the manual windows. I had a bad experience with one of my Ford Tempo's windows and don't want power windows again. Just to replace one motor was $150 just for the part....no thanks.
