Well, sorry for the bump, since I got into this game this year. For me it is the Plymouth XNR Ghia Roadster '60. Even though it is essentially a fancier-looking Valiant (complete with its Slant 6 engine, albeit heavily modified), it looked so good to me that I resisted selling it (the initial plan was to sell this car to get the GT by Citroen race car). The car can be described as a mix of the wild styles of American luxury cars, with the fins and the wide fenders, and subdued, aerodynamic styles of European race cars, with the slim bodywork with a narrow front. Yet the lines blend in so perfectly, to create a perfect harmony. You might have been able to see it in this game, since it is the reward for getting all Gold in the 2nd lineup of the Goodwood Festival of Speed event.
