From the listing for this 1970s Lotus F1 car for sale:

Lotus 78 F1 with Ford Cosworth DFV. The iconic Lotus 78 was driven by Mario Andretti, Gunnar Nilsson and Ronnie Peterson during the 1977 and 1978 seasons. It was the car that started the ground effect revolution as Colin Chapman was the first to use the inverted wing philosophy – and to great effect, with Andretti winning 4 times and Nilsson winning the Belgian GP, and Andretti only missing the World Championship because of engine failure in 1977 before using the 78 in the first part of the 1978 season – winning in Argentina and Peterson winning in South Africa before the equally dominant 79 was introduced which helped Andretti become world Champion in 1978.

In 2009 the car was restored by Classic Team Lotus and the car has been part of a significant collection for the last few years. The engine was rebuilt at the same time and has only been used for demonstration purposes. Offered for sale with new crack test, fuel cell and current FIA HTP papers, as well as 2 set of spare wheels, this is an iconic an emotive Lotus F1 Car and would fit seamlessly into a serious collection.
