typically japanese cars are da best and for fuel economy go with da honda civic or da civic hybrid. corolla is also good. camry hybrid is better cause it is larger and gets a decent amount of fuel economy. i think for da camry hybrid its 33/34. sentra should get like at least 34/36. corolla is da same as sentra fuel wise. you mite also wanna try da acura tl. its epa is 29/31. but the tl is pricey at 38k i think. hope dis helps

Honda Civic and Honda Fit.
They are the class leaders in the compact and sub-sompact class each getting over 36mpg highway and both the most reliable in their segments.
