<prompt> Human: As the title states.. looking for some advice on what is best financially. Current car is 2010 VW Jetta , no mechanical issues, newish tires,140k miles, and most importantly paid off. Insurance is about 79month and I am getting 25mpg. I currently drive about 40 miles all highwayeach way to work, filling up about every 5 days or so. 33 avg each fill up, I barely drive weekends, so it works out to be about once per week or so for a total of 150month I am potentially starting a new job that will be 60 miles edit: each wayagain- all highway which will mean I would be filling up about every 2-3 days...which will seemingly almost double my monthly budget for gas. My question is : do i keep my car because it is reliable and paid off even if the mpg isnt great, OR do I get a more fuel efficient car such as a hybrid or diesel which will incur a monthly payment but would possibly save me in the long run in gas? Im considering a 3-4 year old car in the 15k range... selling mine for about 5k, thus a 10k finance...paying it off asap to get back to zero monthly payment Does it even matter? Is it just a wash at this point? TIA for any thoughts  <response>: You would be better off to keep the current car, saving aggressively to purchase a new car. The cost of the new car will be far more than the little bit of extra gas.
