No one needs a 2m bugatti. Like most people don't really need an Iphone or samsung galaxy with a HD camera and quad core processor. But we do buy it because it's a luxury we can afford. The only difference between us and footballers is the luxury they can afford is way more expensive.
Spot on, I was just about to say the same thing.
If you have the money, why not? If you can afford it, go for it. It may even be personal taste & preference. How many of us would love to own a sports car? Not because of image, ego or any self indulgence, genuinely because of how awesome the car is and the way it looks. You like it, you want/desire to own one which then breaks down into can you afford one, if yes - buy, if no - sorry, get saving.
