I experimented with teaching my son to drive my boxster when he was home on leave. Didn't go too well and all the better anyway. I don't need my clutch ruined.
Here's how I learned years and years ago. Was on a small town dealer lot, fell in love with a navy blue 74 trans am, 4-speed but when I saw it had a stick I told the sales guy to forget it. He said, if I teach you to drive it right now will you buy it? I said ok. The deal worked out well for both of us. I don't think that would happen today!
Eventually I had that clutch replaced because I was so new to stick and was putting some big time wear on it while practicing.
Back in 1979 replacing the clutch/pressure plate was a whopping $275!
