...when we´re talking about
racing cars, definitely the
956/962!!!
its design was simply ahead of its time, it handles extremely good, had the best brakes by that time, stunning aerodynamics performance, was the first car featuring Bosch electronic fuel management, first Porsche car with monocoque instead of tube design, therefore it´s still most successful sports racing car of all time, just some key words: LeMans, FIA & IMSA endurance races, NS endurance races ( 1000km race…), endless list....
last but not least, as lakatu already pointed out, a 956 achieved a nearly unbeatable lap time on NS with 6:11 for the 20,832km track...
street cars......extremely hard decision....CGT or 993 Turbo S, can´t decide...
