Actually, you know what? I will give you some advice.
I’ve had my share of boy racing, I believe in making progress, and for all your willy-waving about your 1.2L fartbox I will beat you off the lights if I really wanted to (which I probably don’t). Against your Corsa, I could probably do it on foot.
Your age isn’t your issue. Nor is your car. Your attitude is your problem, and if you don’t check it then you’re going to end up hurt and out of pocket, or worse.
There a lot of people here who know what they’re talking about (and a few who talk out of the top of their heads). You’d do well to listen to some of them, they’ve almost certainly been where you are now, come out the other side, and dealt with it all over again with their kids.
