I got my PPL at 17 (with one week to spare!), and although I don't have the money to take full advantage of it (at the moment I'm just taking the odd cost-sharing passanger up for a quick local) I'm loving it! I reckon that people are much more impressed if you get your PPL when you're still at school, which is quite fun; I got a mention in a school assembly a few weeks after passing the skills test, which certainly woke me up from my usual Monday morning day-dreaming!
Oh, and yesterday I had a (half) lesson on the club's new Robin DR400 Ecoflyer. We never actully got off the ground due to approaching storms, but the excitement of being in a new aircraft (just 49 hours on the clock, which felt weird) with a built-in moving map and a shiny new cockpit was massive. I would certainly suggest trying a variety of aircraft as soon as possible.
Enjoy yourself,
Proctor
