Well, I don't get rid of a car, unless the cost of repairing it for a year, is approaching having a car payment. At that point, why not just have a new and reliable vehicle? That said, I usually get a butt-load of miles outta them. Unless they are made by GM, but I digress...
Anyhow, I find it really cool, that in eight years, when my son is old enough to drive, I can stick him in the Pat, and still have it under warranty. cause you just know he's his old man's boy, and he's gonna need that coverage. lol.
Aside from that, why not keep the car? In ten years, when it really starts to go downhill, the drivetrain will still be covered. All the little odds and ends that will break in the course of a year, will never amount to what it would cost to pay for a new car by then. In ten years time, I'm thinking it's gonna be at least 5-600 bucks a month to get a car that's equal to the base model Pat I have. At least.
