New car: buy with cash or 0% financing
Cash price is $22,500. Financed, it's the same thing (0% interest) but you pay a $1500 fee. 1500/22500 = 6.6%. Basically the APR for your loan is 1.1% per year but you are paying it all upfront. Opportunity cost: If you take the $22,500 you plan to pay for the car and invested it, could you earn more than the $1500 interest on the car loan? According to google, as of today you can get 1 year CD @ 1.25% so yes. It's likely that interest rates will be going up in medium term so you can potentially earn even more.  Insurance cost: If you finance you'll have to get comprehensive insurance which could be costly. However, if you are planning to get it anyway (it's a brand new car after all), that's a wash. Which brings me to my main point: Why do you have $90k in a savings account? Even if you are planning to buy a house you should have that money invested in liquid assets earning you interest.  Conclusion: Take the cheap money while it's available. You never know when interest rates will go up again.
