Just thought I'd share my experience at the LAS airport location. Had reserved a full-size car at a base rate of $20 a day. At the counter was told I could be upgraded to a luxury car. The script went something like "normally a luxury car goes for $50 a day, but I'll just make it $30." Confused, I asked "what do you mean?" The rep replied "your base rate is $20 a day, but I'll just make it $30." The emphasis both times being "I'll just make it." Thinking, $10 to upgrade isn't bad I agreed, only to find out when I returned the car they had tacked a $30 "upgrade fee" on top of the $20 rate. I have to give it to them, this one is clever, and it's my fault for not catching it on the contract. Very sleazy though, I wish Dollar weren't so cheap so I could avoid them...
