At first, let me say I'm glad we agree on the choice of music! Secondly I would never be mad or jealous at anyone because they can afford something I can't. The fact that there are a lot of people here in Germany who are notoriously jealous, is one of the things I don't like about my country. Here the thinking seems to be "Why can HE afford that and I can't! So unfair hurrdurr!!!" whereas in other countries, especially the US is more like "Good job on earning yourself that!". In my perception at least.
You did just fine proving a stereotype wrong that is non existant anyways,
Actually I don't like any of the stuff you mentioned. The more HP the merrier, but why shout about it. Enjoy the fact your faster, show it at the track, but going all "in your face" with number plates or stickers or stuff like that isn't what I find cool. In fact I think it's childish. Destroy perfectly fine tires? Hell yeah, on any trackday or drag strip!
