Classic Car Insurance Hagerty vs Grundy

How do the other companies handle racing?
I was up front and told the Hagerty rep on the phone that I intended to drag race and possible Autocross the car. I was told that Hagerty will insure the car but the coverage is not in effect while the car is being prepped for racing or participating in on track events. I will get a better definition on how Hagerty defines 'prep for a race'
Grundy and American National both declined to write any coverage on a vehicle involved in racing.

I called Hagerty again, the person that I spoke with said she did not know what the other Hagerty rep meant by saying the car was not covered while being prepped for racing.
She confirmed that the car is not covered while on the track, but while it is being driven or trailered to the track or while the car is in the Paddock area the insurance coverage is in effect.
And post 26 is a bit different from what the Hagerty agent just told me, that may be a difference between Hagerty insurance in Canada and Hagerty insurance in IN in the USA. The bottom line is, get it in writing.
