Found the best deal with Budget, a "street fleet" Mustang for $83 a day BEFORE the $40 a day in taxes.
Of course, I have a Hertz Premium full sized in Houston for 3 days before this for $65 a day and only $17 a day in taxes.
Keep checking. We live here, but decided to rent for our last trip DL to save wear and tear on our other cars. Just about three weeks ago we paid $90 total for 3 days. Not sure if it was because of the time of year or the fact that it was very last minute, but we jumped on that rate. It was from Payless, but even costco had low prices.
