<prompt> Human: EDIT: Thanks everyone for your input. After reading through all the varying suggestions, I am going to table the purchase of a USED but better sports car for at least a year until my financialSOs situation is a little more clear. In reality, my 2004 350z is a fun-ass car, so I think Ill be just fine although I may upgrade my motorcycle which is a significantly cheaper purchase. I appreciate all the time you took reviewing my situation.---I am 27 with an 88k annual salary, about 40k in debt most of which is student loan which I am paying above the minimum, about 8k is a recently purchased engagement ring at no interest for a year, no CC debt, about 20k in the bank, am contributing to a Roth IRA for the last 7 years or so, and as of recently a 5 match 401k is available through my company that I will take advantage of. My credit dropped from 795 to about 740 due to the ring loan. Also I pay 1k for rent per month.I love cars. I have an older sports car worth about 6k that I own. I want to get a better sports car worth about 25-30k, and finance it obviously. And Im aware of the additional cost of this ownership, like higher insurance, property tax, maintenance cost, etc. Looking at loans for a private sale that at the lowest would be 4.25 interest, monthly payments would be about 500 until I sold my current car, and I think I would put that money toward that loan.Is this a bonehead financial decision, to get this nicer sports car? I do see myself getting a house in the next year or two. My SO currently doesnt make a lot as shes completing her doctoral program, but has high income similar to mine in the near future. She also has excellent credit and decent savings, but also a good chunk of student debt.Ive also been reading things about how even if I had enough to pay off the car up front, thats silly because if I invested that money, my return would be much greater than the interest Id be paying. Should I have a similar outlook with that 6k from my car if I sell it?Some advice would be great, thanks!  <response>: In your words...this is a bonehead financial decision.If you sell your 6k car first, its still a bonehead financial decision.
