The worst car I ever had was a Ford Fairlane that had a rebuilt engine, new everything but had a ghastly fumes leak from a hole in the floor!! This was when my daughter was only 2 years old. I had to drive with the windows wide open during the winter so we wouldn't get carbon monoxide poisoning. I ended up junking it and buying a used VW bug with no heating system (the heater coil blew and couldn't afford to have it fixed). Everytime time I got in the car, I'd have to scrape the ice off the INSIDE of the windshield!! Come to find out it had been in a major accident and was completely rebuilt. That's when I SWORE I would NEVER buy another used car again.
