I got a 2001 Ford Escort for free, and surprisingly I got about 5 years out of it with nothing but fluid changes, brakes and tires.
It wasn't even the decent ZX2 model, but rather the fleet only SE. It was never anything but an atrocious POS, but it also refused to give up the ghost for a very long time. Eventually, the strut towers rusted and I decided to cut bait.
I both hated and loved that car. It was awful in just about every way, but there's a real liberation about having a free car. You don't care if someone bumps you in a parking lot, or doors you, or if you back into a pole. The car will never be worth any less than you paid for it, so you never have to worry.
