We're not rich, we've been doing good for a few years which is different.
But it's a very vulnerable business. My parents have had to start all over from 0 once or twice.
Last time was 13 years ago, after the twin towers were destroyed. USA stopped exporting/importing, that froze the whole world's industries.
My parents' company had no work during a huge period, and it was a society between 3 companies. We had the A4 at that time iirc.
My parents had to mortgage the house and risk buying the whole company, and hoping to be lucky enough to get work back again soon.
They had to work to pay debts of over 100.000€, due to having bought the rest of the company, my father still does all nighters working when there's a lot of demand, and he's done two all nighters in a row if necessary.
Things get built with hard work, at the moment we're doing good, but if the USA or Germany fart at the rest of the world things can go downhill fast. That's also why it's important to save money, incase hard times come in like a wrecking ball out of nowhere^^
So this also answers why not getting the M5 even if you can afford it, my parents decided for the m550d because they can afford it and still save up what they think it's a safe ammount. perhaps the savings would be lower with the m5.
So it's easy to point "Rich" like some people do when they see we buy new stuff, but no one takes some moments to think, perhaps they deserve it, they've had some worse moments, and they've worked hard to build what they have now. They deserve some treats perhaps! Don't just go around saying people are rich because they own this or that xD
We're doing good at the moment, each year better and I really hope things keep this way, but to be rich we have to be sure we'll still do good in some years, and that's not something we can take for granted!
