I too am with Chartis (the BJ endorsed program) and they have always been extremely courteous. Admittedly I have not had to claim fortunately, so no experience there.
I switched from American Collectors 2 years ago because Chartis premium was half what I was paying. I can't break out just the Pantera's from the total but I have 4 cars total insured value $280K and I pay $1280/yr, zero deductible.
