So, say you were to have a car. Pretend this car was a 1991 Toyota Celica on it's last legs, that you were planning to get rid of in a month or two anyway. Now imagine that where you live, a huge, nasty hailstorm came through, and knocked out the back window of your Celica, along with causing a good dozen or so hail dents all over the hood and top of the car.
Are you with me so far?
So what would you do? Remember, you're getting rid of the car in a few weeks, anyway, so is it worth spending the money to get the back window replaced (not even worrying about the hail damage)? Or would you just tape up the back window with some plastic and bear with that until you get a new car?
(Oh, and also, you only have liability insurance, because your car's a piece of sh!t, so having the insurance pay for it is not an option.)
