Bad news tut, as long as no one was hurt and he learns from the experience, which hopefully he will rather than thinking he's invincible because he walked away from it. The young adult male mind works in odd ways.
It took quite a bad accident to teach me the lesson. I wrote three cars off by the time I was 21*, the last one being a Talbot Lotus Sunbeam that had been my uncles. To this day I hate Simon Bates as that was the only bloody radio station I could get on the radio and that soppy programme (Our Song or Tune or something) of his came on one afternoon and I promptly hit a tree while trying to find a tape. I couldn't afford another car so bought a motorbike which I put up a bank 3 months later putting myself in hospital for 2 weeks. My mum also banned me from driving anything for a year and took a classified advert out in the local paper telling everyone

Anyway, I've never had an accident since, well apart from the bloke that reversed into my current Elise a few weeks after getting it.
BTW My 4th car was a Vauxhall Viva called Sally my uncle bought for £50 so threaten to buy him a sh*t car with a girls name. I never had Sally long either as it got nicked and burnt out 200 yards from the house. Our view was that it broke down and spontaneously burst into flames however. After that it was all company cars until the first Elise.
Kids, who'd have them eh!
* The 2nd car I wrote off was more that I lightly kissed a fence at very low mph and the car fell apart around me so technically shouldn't count
