<prompt> Human: Hey guys... Two years ago, I have bought a brand new car for roughly 50k. I am considering selling it and rent a brand new one that is roughly in the same class luxury sedan instead, but I am still not sure if its a good idea or not.Some background information about myself:I work at a top 50 fortune company, in Europe. My salary is 85k 50k after taxes and since Europe doesnt really give you a choice, I dont have to pay for health insurance, road taxes and so on due to higher taxes. So I take home around 4k after taxes, out of which 1k go on rent, food and all other expenses. My wife works at the same company too and she gets around 65k 35k after tax and we split the bills. So overall, our monthly income after taxes and after all monthly expenses are paid off is around 5k.Now I am a car enthusiast and I would love to upgrade my car to a newer model. I could sell mine for 30k and rent the one that I like for 1.1k a month, including insurance and service.My thought is that the more I keep my car, the more I will lose on it, especially after it hits the 100k km mark currently standing at 87k. Moreover, I get to bank 30k which I can use for investments, instead of keeping dead money in my garage. Do you think its wise to just keep the car that I currently own?Edit: typos  <response>: The 30k that you think youre saving for investing is not going to make you any money unless youre getting at least a 45 return on it and that insane.
