Just had something very odd but very good happen for my rental August 4th - 9th. I had my res booked with Alamo at $210 with a Full size (week rental) and a coupon for a one class upgrade. I have been checking and noticed Dollar/Thrifty deeply discounted only their Premium I got the week for $96, with a 10% AutoSlash coupon. Total is $160 with taxes. You might want to check if your travel is in the next couple of weeks. Looks like they are trying to rent out inventory. What is odd is that the other classes, even compact, pretty much stayed the same. Only the Premium cars dropped.
