Chevrolet Cavalier
The Cavalier was one of the most popular and underrated cars in GM history. It was sold across many platforms and styles. But the first generation cars were cheaply designed to say the least and the pinnacle of what made 1980s compact cars awful. A buzzy, unreliable engine and a cheap small design were at the forefront of the problem (via Hemmings).
The Cavalier was a notable car for GM because it was designed to appeal to consumers who wanted a budget-friendly compact car. The fuel efficiency of the Cavalier was a major selling point, but the build quality was lacking at best. There are old compact cars worth checking out, but the Cavalier isn’t one of them.
