I read in another thread that those of us planning to rent a car can search car rentals in this site, but I can't find anything. I'm looking to make sure the company (Dollar Rent A Car) we have reserved a car with provides good service (ie: if the car breaks down along the way, that they would help, etc). Its the best price we could find online ($640 for 2 weeks + 1 day, unlimited mileage nationwide...then we'll have to pay $5 day for an additional driver...premium size car..chrysler concorde). Any experience in this area?
