1971 to 1977 Chevrolet Vega
I have a small confession to make. I know the Vega is routinely derided as the worst-ever vehicle ever produced by Chevrolet, but I kind of like the way it looks. I think, in my heart of hearts, that the Vega is actually a little sexy.
Some people actually agree with me. Heck, even Motor Trend named it the 1971 "Car of the Year," and around 2 million examples of the Vega were sold between 1971 and 1977.
Regardless, most people are rightly fixated on the Vega they remember driving: a rust bucket that shook and rattled on down the road, burned oil like lanterns, and overheated on a regular basis.
Critics of the car contend that it was a good idea wasted on poor execution, and that Chevrolet rushed development, cut costs, and was too focused on fuel economy. I'd say that's a recipe for the worst-car-ever list.
