<prompt> Human: This weekend Ill be making a 1400 mile road trip. So I decided to look into renting a car. The rental car is a 2017 Toyota corolla. I can rent it for unlimited mileage for the number of days for 87.Using the car reported miles per gallonMy be Subaru Forester gets 27mpg. That its 52 gallons of gas 2.29 per gallon 119.Corolla gets 40mpg. Thats 35 gallons of gas 2.29 per gallon 80The Corolla will save me 39 in gas, which now brings my rental cost to 48. Is it worth paying 48 to save the Subaru from 1400 miles of wear and tear?  <response>: Yes, its worth it. Gas is just one factor of the cost equation, you have wear and tear too. IRS rate for auto deductions is 54 cents mile. If you look at it that way your rental would save you 592 756 for 1400 miles less 87 rental less 77 in gas
