<prompt> Human: My boyfriend makes about 65k in a super stable field, were both 24, and hes looking at the Lexus IS350. This is after I talked him down from a BMW 3-series because thats just a money suck. I dont want him to get a car because I think that there should be no reason to buy a car at our age when we already have reliable working cars. Especially a luxury car. Any extra money we should make should go towards investments, because time value of money, right? Its creating sort of a weird rift. On a deeper level, I feel like its a reflection of our different values. When I want to make a dumb big purchase, I would much rather travel. What are your thoughts on this? Edit: Thank you everybody for the feedback, and helping me think through this. I came to rpersonalfinance to see if there was any possible reason to feasibly purchase a 40K car at our ageincome without making significant sacrifices to investing, other activities, etc. Many agreed with me that it came down to what we valued spend to save vs. spend to treat yourself now. If youre here to tell me to not tell him what to do with his money, I dont. Period full stop. If he asks me for advice, Ill tell him re: BMW. But ultimately, Im trying to understand for myself, because this again is a deeper conversation about our values. Which I think is important in any relationship, but to each his own.  <response>: A 40k car on 65k a year is too much. Unless of course, he already has enough assets to be able to retire right now and is just working for fun which it sound like he isnt. You might remind him that if he invested 40k right now instead of putting it into a car, it would be worth nearly 1 million dollars by the time he is 65.EDIT: I also think you are completely justified in your weird feeling about this. You are both young, will make mistakes and arent weird, but this does give a glimpse into his irresponsibility with money. If money is an issue now, it will more than likely continue to be a problem.
