<prompt> Human: Long-time lurker. The fact Im writing this scares me because Im usually smart enough to say no to big purchases, but this time Im tempted.I want to buy a Porsche. More specifically a 2013 Carrera 4S. I dont care too much about the amount of miles it has, but would prefer a certified 4S from a dealer. I expect this to run me 75k - 85k, but I 100 willing to wait until early next year so maybe the price will be a bit less. My fiancee says its a dumb decision, but she really doesnt care and said if it make me happy then go for it.Back story: Ive loved Porsches since I was a little kid and now might be the best time for me to get one. I recently moved from NYC to the Bay area. Im not sure how long Ill be here, but 2-4 years is my guess. The Bay area, especially where I live and work are more car dependent than NYC. Also, the roads out here are also really really nice. I would not own a sports car in the NYC area unless I spent most of my time in the suburbs or in farming towns. I strongly believe self-driving cars and Uber like services will make it impractical to own a car in as little as 6 years.Perfect storm?Finances fiancee and me, both 31: Stocks - Roughly 60k Emergency Fund - 35k Retirement - 95k mostly her, she maxes out 401k and Roth Future House Fund - 50k Cash on hand - ranges from 20k to 30k Salaries - 75k her, 150k me Bonus - 50k-150k me - 50k is guaranteed, and 100k is very very likely. Paid out at the end of the year. Equity - roughly 200k in my current employer, but not sure ifwhen this will find liquidityExpenses Two apartments - 4450 combined - bicoastal living for the near future. Hopefully changes in 2016. We each spend roughly 1,000 a month on foodclothingentertainment. I sometimes take it up an extra 500. The kicker - roughly 100,000 in grad school debt. I make double payments for a total 1,400 a month. Im more upset that Im not using my degree, than I am the payment. Mistake made, lesson learned?Back East we have a paid-off 2010 Audi A4 with 45,000 miles. We put less than 4,000 miles a year on the car.With the Porsche I will probably put on even fewer miles. Less than 3,500 a year is my guess. I live a few blocks from my office and will continue to walk, except for street cleaning days. This purchase is more about having fun, visiting friends in nearby cities, grocery shopping, driving the coast when the fiancee is in town, etc. Ill likely sell the car whenif I move back to NYC.We also have zero desire to buy a home right now. We believe the cost is too damn high and we travel a lot for work. We rather wait until there is another down-turn in the market then pounce.Were planning a court house wedding and a small dinner.Hopefully no kids in the next 3 years.Our jobs are for the most part stable, but I dont think anything is truly secure. I think were employable and if one of us were to lose our job wed get out of one of the apartments. If the economy gets better we expect our incomes to rise. Someone stop me. I know we I really should be saving more, but...UPDATE this is exactly the advise I needed. Thank you everyone. At the end of the day I really should be saving more, especially when it comes to retirement. I would like to be semi-retired by the age of 50, and spending big money on a car I will only drive for a couple years isnt worth it no matter how much I want it. Thanks guys for convincing me to step back from the ledge.  <response>: 31 years old, 225k in salary, 50-150k bonus...Yet you only have 95k in retirement? And somehow owe 100k in student debt? Brother, youve gotta pay that debt off and jack up that retirement before you even think about buying a 75-85k car, unless you want to work until youre 100
