Try pricing Blizzaks at another tire dealer. I got a quote from Firestone, although the guy didn't ask what kind of car I owned.
I went to an independent tire dealer to price a set of Nokian snow tires, and at the same time got a quote for Blizzaks. This fellow knew I had a hybrid and didn't seem to have a problem with it. The price for Blizzaks was practically the same at both places.
