We found another company that looks like it may be able to provide car service from Bologna to Florence. I am a little unsure of their name - the title of the page is "Private Tours in Tuscany, Italy" - the URL is http://www.prestigerent.com, and at the top of thier home page it says "PRIVATE TOURS IN TUSCANY". They appear to be a tour company, with car and mini van service. We have an email in for quote and will post their response when we get it.
