<prompt> Human: To preface this, I came into a significant amount of money from a lawsuit in 2014. Im trying to comprehend what exactly someone in my position should spend on something like a car.Once I got the money I paid off all student loans I had, all of my debts, bought a home bought for 305k, now worth 415k, and met with a financial advisor to put me on a correct path. I currently have a little over 300k in the bank, and Im making a bit over 20k a year from my investments around 7.My bills:HOA dues total 360 a monthProperty tax is nearing 2500 yearlyPhone bill is 70monthCar insurance is 120monthUtilities total 400 a month which is pretty high from what I can tell, but mostly because of some luxuries I like to have.I just recently graduated college and yesterday received a job offer at 85k to start software engineering including a signing bonus. One thing Ive always wanted in life was a nice, fast car. I know thats probably a terrible financial decision with how awful depreciation is and whatnot, but Ive been severely eyeballing a used P100D for 108k, and after test driving one not too long ago, my mind is telling me to buy it.So heres my question. How exactly do I distinguish how much money I should spend on a big ticket item when I own outright the other major big ticket item, my house?For example, the 28 rule on housing and the 15 rule on transportation. Because I own the house outright, is spending up to 43 on transportation a terrible thing? Id probably just pay in cash instead of financing even though Id be well under the 43 considering I have the means, but is that even an advisable decision barring the whole depreciation thing for someone in my financial situation?I appreciate any insight, thank you very much.  <response>: Terrible choice financially. While youre doing a lot better than most people your age youre hardly in a position where a 100k car even remotely makes sense. If you continue making decisions like that youll burn through the cash quickly. What happens in 2 years when youre bored with the Tesla? Time for an upgrade? How much is insurance on a car like that for a young kid? Horrendous I imagine.
