TBH, we gave them a pretty easy job. My brother was a bit of a so-and-so in his tweens and early tweens, but we were quite nice teens.
I realise, having seen my DH do not so well at this, that our parents never snapped at us, so we didn't learn to speak to one another disrespectfully in our family, and I don't think any of us would have dreamed of being snarky at my parents, so we never were.
They gave us trust and in return we didn't want to betray that trust by doing anything (too) daft. It made life easier that none of us went out before age 16 (maybe as we all looked very young) and rather than bothering with curfews the rule was basically we told them what our plans were for the evening/night and if we might stay over someone's. And because they hadn't been gits to us, we were honest about what we were doing.
We weren't angels, there was a fair amount of drugs (certainly in my older siblings' case) but we had mates, were doing well at school, so there was no reason for them to be on our case - they picked their battles. Things like clothes, music and hair were non-issues (in fact my mum loved and encouraged my weird style, dyed hair etc)
Sadly watching my DH's parenting I realise how you end up with sterotypical teenagers - DD (12) is already slamming doors and overreacting, particularly with him, and not wanting to be honest with him when things go wrong. I predict warfare and also my kids telling me to keep things from their dad once they hit their teens.
