Enterprise Rent-A-Car again offers select car rentals from $9.99 per day (for up to 100 miles per day) on most weekends at most neighborhood locations. (Airport locations and select metro areas are excluded.) That ties our August mention and is among the best such offers we've seen from Enterprise Rent-A-Car. It applies to compact or economy class cars rented on Friday and ending the following Monday. Of note, fees, insurance, and taxes are additional and may be substantial. Deal ends May 22.
