Wow wow wow... bad bad bad...
I firmly but politely declined the additional insurance that as others noted is forcefully up-sold by their counter staff. Luckily, the sales agent did not push further when he saw my fortitude.
I had my choice of three economy cars. I chose a Chevy Aveo, not known as a nice car, but also not known to come apart in pieces while driving slowly in street traffic. The first sign of trouble was when I exited the car rental site, and attempted to lower the sun visor to avoid being blinded. Instead of obtaining relief, the visor came loose in my hand, causing much panic in the car. Thankfully, I coolly avoided a potentially serious accident. It only went downhill from there.
The creaking, rickety jalopy I received for the money spent is simply not a good value! You may "sav mor" than if you went to some other agencies, but you are bound to not receive a good "valu!"
