<prompt> Human: I drive about 3000 miles a month for work. I am getting paid mileage from work. right now I am driving a car that get 27 mpg average. so it cost me about 14 cents per mile. paid 55 cents per mile from work. my car will be paid off this summer but it is nearing 200k miles. would it be worth a switch to hybrid 55mpg car. I would halve cost per mile to around 7 cents per mile. is it worth the upgrade to have better mileage but have more car payments?oil changes would be every 10k instead of 3k so about every 3 months for oil change instead of every month. insurance will go up since it will it will be a newer car. is it worth the upgrade or keep the older car.  <response>: Youre only looking at the cost of fuel. The real cost of driving is much closer to the 55 cents than you think when you factor in insurance, wear and tear, oil changes, etc. I dont know what your car payment is, but Im sure it can buy a lot of gas every month. It still may be time to look at a newer car assuming your current one isnt running well, but I wouldnt base it on your mileage credit.
