I know there is a street version of the toyota gt86 that raced at the 24 hours of nurburgring which has tow hooks, its in the toyota dealership. Other than that, I'm still exploring sea of cars.
The Subaru Challenge car, based off there win at Green Hell in 2012 has tow hooks as well. So far adding them to any car is not an option I see. Just on a few cars that have them by default.
