I bought a 2001 insight last spring for $1200 with 224,000 miles on it. I haven't done a thing to it and can get 68 mpg tops. (I like to drive between 65-70) I live at 1400 feet and there are a lot of hills. I have noticed two grounds not connected on the right side when I purchased it and just haven't gotten around to fixin it yet. I had no idea it could effect gas mileage. I will eventually get under the hood and check the EGR and plugs as mentioned. I am now at 236K and probably should get around to it. Thanks for the info
