grand prix

Would you call your driving school "Grand Prix?" A driving school in Manhattan??? I was walking down Park Ave. today, and there, parked by the curb, was a car with a Grand Prix Driving School sign on top of the car. I didn't get my camera out because it was cold and snowy and I didn't want to delay my trip to the subway, but there it was. I've seen this car before. If I see it again I'll take a picture.....
