Classic Car Insurance Hagerty vs Grundy

Check with American National.
early on in the on line application form is the question "Will the vehicle be used in Racing events?"
I checked the Yes box and the response was with Racing involved the vehicle is not eligible for American National Insurance.
A pop up box opened and said to call 1 800 CAR BUFF, I did that and got an agent at American National who again said with racing involved the car is not eligible for American National Insurance.
How do the other companies handle racing? Probably the same. We should ask our racing buddies here to see if their cars are covered somehow. @pittsburghracer ?
