Apparently, it is an existing business. I doubt they'd consider selling it unless you can sign and empty check covering all their rebranding costs and few years of their cash flow from running the auto business to make it worthwhile.
I don't think Californians can buy .CA domain, unless they are Candian citizens. To register a . CA domain name you need to be a Canadian Citizen, a permanent resident of Canada, or an organisation in Canada such as a corporation.
