I have three cars with Grundy, yes there is restrictions with type of use, but they do not interfere with how we use these three cars anyway, but there is no limitation on miliage during the year, and yes the cars must be stored when not used within locked garages, like who would do otherwise anyway? For sure your age, driving record and even what part of the country you live determine the cost. Example: we used to live about 45 minutes from Philadelphia, Pa. when we moved back to Ohio where we live now, the same cars, same drivers etc., our preumium cost dropped nearly $400.00, this was our daily drivers under what would be considered "standard" insurance. Not specialized insurance for classic cars.
But I will check with Taylor, never heard of them before.
