Safeco isn't reliable at the best of times. And nobody is more reliable than AAA roadside assistance. Nobody. Thank god their auto insurance is nowhere near as good as their roadside coverage, because if it was I'd be out of a job. Or working for them.
AAA (called CAA where I live) is THE name in roadside assistance coverage. Other companies say they compete with AAA, but very few of them actually do. Don't take my word for this, I wouldn't trust me and neither should you, so do a little digging. Call up anyone who offers roadside assistance, and ask them how good they are. Every one of them, every single one, will say they're just as good as AAA.
Notice how nobody claims to be as good as National Auto League, or as good as Safeco, or Dominion, or Chico's Liquor & Guns & Towing Service. Nope, they all say they're as good as AAA. That's not a coincidence.
