Seems as if I'm the only one interested in this thread but I'll post anyway. I went to Lime Rock on Monday for the final Historic Grand Prix race. 9 cars were entered, with 6 or 7 non competing cars sitting in the paddock, including the original Lotus 79 test car. Cars racing were the Lotus 79, Williams FW07, March 761-08, Penske PC-3, Wolf WR6, Ensign, March 811, Hesketh 308, and Brabham BT-37. The Williams and Lotus were fighting pretty closely setting best laps in the 47's. I watched from the outside of West Bend and seeing the Lotus 79 oversteering and twitching on the exit was incredible. The race was unfortunately interrupted by a few caution laps due to the throttle sticking on the March 811, but for the short time the cars raced it was well worth it. I took quite a few pics as well -
