I would recommend looking into credit cards as well. Mine offers coverage for rentals, however, it doesn’t offer liability insurance. Since I only rent non-zipcars maybe 6 times a year, tops, I was curious about non-owners insurnace as well. My only problem is, I don’t want to pay out the nose for it. I have State Farm for my renter’s insurance, so they are probably a good starting point. Bundling services tend to get you better prices for insurance.
