I have a 2005 Toyota Corolla CE and I just rolled over to 100,000 miles. I’m perfectly happy with the car and I’ve had no problems. I get regular oil changes and keep my tires overinflated. I am interested in getting better gas mileage as this past winter I’ve been averaging about 30 mpg. Over the summer I was getting about 35 mpg. I’ve read what you said about weight basically being the most important determinate of gas mileage, so I was wondering what you suggest if I want to make my car lighter without spending too much money.
