oh my god I can't believe people think it would take 6 months! either those people have never driven or are absolutely untalented! normally people can 'drive' after their first lesson, 'driving' itself is not that hard, it's more about traffic rules and parking manoeuvres and stuff like that, but as you said you drive automatic already I assume you know all that, so I don't think you will need more than one single lesson! manual driving is really not that different!
