<prompt> Human: Im 23 and my fiance is 28. One thing I have always likedadmired in him is that he was very smart and diligent about saving for the future. His family earned an above average income but always lived like they made a lot less and now his parents are sitting on a very large, comfortable retirement account and they still live modestly!.I have also always tried to live modestly to be a responsible saver. I graduated college with zero debt from work and now am putting myself through grad school. My fiance taught me about investing and I was proud to have put away about 12 thousand into a 403b my first year working. He on the other hand has literally had an investment account since he was 18.My concern here is that after years of living reasonably I would not say he has sacrificed happiness for frugality by any means he suddenly wants to buy a newer Nissan GT-R. This is a totally unnecessary supercar that he has unwaiveringly set his sights upon. He claims to understand the cost of ownership and maintenance, and doesnt want to compromise on a cheaper car.Currently he makes about 80-90kyear. He has a hair over 155 thousand in his IRA401kinvestment accounts.He has a 220k mortgage with approximately 110k in equity in his house.As you can see, he has done very well for himself by being smart with his money. Now he wants to buy this GT-R at a cost of around 65k with untold maintenance costs. He plans on putting down 15k and his credit union will finance the remainder at 1.99.He has a stable job, and I will be earning about 100kyear when I graduatenurse practitioner, but thats still 1.5 years out. Is this expense insane for his current income, or am I crazy? We have been discussing this a lot but hes adamant he can afford this. Im worried, but he ultimately does understand finances better than I do.  <response>: A Nissan GT-R is a car for a person that understands what kind of car it is. This doesnt sound like its a car hes purchasing just to have something to drive around... Sounds like hes been planning this one for a while. While I strongly suggest cash up front in total for a car like that, he may have thought on it and decided to go for it for the deal the vehicle has may be saving more buying now with interest on a majority of the vehicle versus waiting for that deal to ever be seen again. Would I go with this purchase? No. But its also hard for me to judge considering I make 13 of what he does. It sounds like hes thought about it... You have a good reason to be concerned, but it doesnt sound like hes lost his financial reasoning considering the rest of his background. This just sounds like his dream car.
