I had a problem with a luxury rental at my local airport. The gave me the keys to a Lincoln Town Car, which was fine, get out to it, start driving and in order to even try to drive straight you had to hold the steering wheel at a 45 degree angle, and if you tried to center the wheel, it would veer hard to the right.

Returned it, explained the problem and the desk employees were generally very concerned. They looked around for a bit and the best they could find was a Ford Edge, which had over 20,000 miles and smelled of smoke covered up by bad deodorizer. I figured the next morning I'd resolve it and swap it out.

Now of course the swap didn't happen because they had no vehicles and if it wasn't for my going well out of my way, I would have been stuck in the Ford Edge. After driving 40 miles round trip I was given a Cadillac DTS with a few thousand on the odometer.

I wrote Hertz, explained the problems, the inconvenience, time, gas, etc, and just received the generic reply. Now I can understand running out of a class of vehicle, but they weren't even offering to reduce the rate, etc. I love Hertz for the Prestige Collection (which is what I mostly rent), but if outside of the areas with this service, the vehicle quality is subpar for the most part and that is sad for me to say.
