Chevrolet Nova (Corolla)
The old Toyota Corolla models have continued to rise in value, but perhaps one of the rarest models was the Nova. The Corolla-based Nova was an interesting concept and the first car in a series of partnerships with GM. Believe it or not, Toyota sold the Cavalier overseas as a Toyota, as well as part of this deal with GM (via Car Bibles).
The Nova-based Corolla was a cheap car in many aspects, and other than the rare sports version, this car should be avoided. Compact cars from the late 1980s are a dime a dozen, and the Corolla-based Nova gets more attention than it should. There were far better options on the market than this one.
