Beyond cost issues, grey market cars provide consumer access to models never officially released. Before 1987, the Range Rover and Lamborghini Countach, both revolutionary designs, were grey import vehicles in the United States. The grey market provided a clear signal to these manufacturers that the United States had significant demand for these cars, and their present-day US model descendants remain popular. Years later, Nissan similarly decided to sell the GT-R in North America after seeing how many people were importing older Skylines. Although Mercedes-Benz was also a beneficiary of the signals to US consumer demand that the grey market provided, their lobbying in Washington succeeded in virtually ending the US grey market in 1988.
