Chevrolet Monza Estate Wagon
This was a strange and obscure model in Chevrolet’s history. It was a crossbreed of two cars, the Chevrolet Monza and Vega. Both of those models were economy cars from the ’70s, which were produced in big numbers and were quite common on the roads. However, for the 1978 model year, Chevrolet Introduced Monza Estate Wagon. It was, in fact, a Vega with a three-door wagon body (via Automobile Catalog).

The base engine was a 2.5-liter Iron Duke four-cylinder unit, but the bigger V6 was available for some areas. Since the Monza Estate Wagon used the leftover Chevrolet Vega bodies, it wasn’t a particularly desirable model, and Chevrolet produced less than 3000 before discontinuing it in late 1978.
