I just rented a 2011 5.0 for a week through Avis. I put 2,000 miles on it within 5 days and loved every second of it! I have an '03 Cobra and must say that after renting the 2011 it's made me think twice about possibly making the switch to a 2011. Ford did an excellent job with this car. Here are some pics:
It was about $100 bucks a day......I rented it for a business trip, so the cost was covered by the company. However I wouldn't mind renting it for a weekend again, it was so enjoyable.
