I'm curious to know what's the longest you've ever driven a car you've owned? The longest car for me was my very first car. I drove it from 1996 till 2000. It was a ford LTD and I drove it everywhere. I even drove it out of town. The main thing now is to just make sure all of your fluids are good and that everything is working properly. Being sure of that and tending to general maintenance will make your car run forever. I wish I knew more about cars back then as I do now, and I would have saved some money and cars.
