Rental car savings tip

Here's how to get a 10% discount on a car rental without even asking! Exchange your car somewhere en route and complain that the brakes "sounded weird" or that you had some other problem. This past week, I realized after a few miles that the brakes on my Avis car felt really jittery, which I think means that the brake pads are warped or something like that. I called the 800 number for roadside assistance and then exchanged the car at the Hartford airport, with no hassle. When I returned the car a week later and got my receipt, I saw that they had given me a 10% discount. The same thing happened to me a few years ago when after driving a few miles while sneezing uncontrollably, my travelling companion and I discovered that the back seat was covered with pet hair that hadn't been vacuumed out after the last renter returned the car. I think that one might have even gotten us a 15% discount!
I don't recommend inventing problems with cars just to get a discount, but if you are already on the road and are dissatisfied with anything about your car, exchange it the first chance you get and chances are you'll save a few bucks.
