Whatever you do, steer clear of Enterprise...
we are currently in FL for a graduation and my SIL's family rented a car from Enterprise to meet us here. on the way, they had a flat tire. Upon inspection, that tire that went flat as well as another one were literally "bald". When my SIL called Enterprise, she was told that they would send someone out to change it but it would cost $60! She was also told that she could not get another car b/c she was no longer in the state where she initiated the rental! So, my BIL changed the tire and they had to choose between backtracking 3 hours to get another car or going to a tire retailer the next day to have tires replaced. I couldn't believe it! You can imagine how my SIL felt. Anyhow, I can tell you we will never rent from Enterprise...and IMO, they are lucky that the bald tires didn't cause an accident, that would have been a whole heap of trouble for them if someone had gotten hurt due to their poor upkeep of their fleet...
