Got forced into Rental Liability Insurance by the agent at the counter. She said it was legally required by the state and that I was not covered otherwise and couldn't rent the car if I didn't buy it. Total scam - your regular car insurance covers this.
You just don't have the time to sit there and argue with them for 30 minutes after taking TWO shuttles from the airport. ACE should drop this company because they are ruining their name.
