What is the Biggest Car Buying Mistake You Ever Made?

          I can think back to my younger days when I was in a hurry to buy a car. I made a few mistakes, paid too much, and ended up with a jet black Nissan 300ZX sports car in time for a snowy Wisconsin winter. Looking back, the mistake was not too bad. I enjoyed the car, paid it off over time, and did not mind driving five miles per hour during snow storms with my rear wheel drive ROCKET of a car. Zoom, zoom, and zoom!!!
