I'm planning to get a used car (1998-2001 models) because of the rise in fuel prices and just wanted to know which car gives move mpg at 70-75 mph highway? I don't like driving at 55 to save gas, so that's not an option. I'm guessing the Honda civic gives less mpg at that speed, since it reaches like 3500 rpm when i'm at 75. I had driven a 2003 toyota matrix XR manual transmission and I drove it at like 75 mph (interstate journey) and it gave me 34 mpg. Any ideas?
