I currently drive an 02 corolla. It has 190k miles on it. The car still runs and drives down the road just fine (other than needing new struts) It was a car that was given to me free by someone who didnt really take that good of care of it. i currently only drive it 3 miles each way to work (looking into getting a bike, but havent really found anything that will fit me, i am 6'8"). The car currently only gets about 24-26mpg per tank of gas. As i said it wasnt taken that great care of, and that generation of corolla are notorious for having sludge and oil leakage, due to lack of holes in the piston rings.
My question is, i have been thinking lately of selling my corolla and using the proceeds to pick up a used civic. Would the difference in improved gas mileage be enough to cover the cost difference? I could get 1500 maybe 2k for the corolla and i constantly see civics on craigslist for 3-5k.
