To go back to the original point; I think a lot of people are guilty of lifestyle creep. If you can possibly afford it you should get it.
That coupled with very effective marketing and well trained sales people; you may end up buying the Audi when the Skoda did everything it could do, and met all of your needs. Then if we can afford the nice Audi why not get the Mercedes? May as well get the 19 inch tyres and leather seats etc.
Then the method of payment is swiping a card or doing an online transfer. If you have to go to the ATM or bank and physically saw the €100,000 you had to hand over for the fancy car, I think most people would pause and have a reality check.
But to each their own....
Some people like fancy clothes. Some people shop in Michael Guineys. Some have several expensive watches, some have a swatch, some use Nivea, some use Clinique.
I have to earn around €166 to pay for something that costs €100. I would not buy a €166,000 depreciating asset that is guaranteed to be worth nothing in time (classic cars excepted here)....
