The Hertz Adrenalin range is awesome - isn't it great that you can book proper American muscle through a fully insured, no limits (i.e. mileage and damage) mainstream organisation. The fact the cars are probably shite doesn't even come into it....it's all about experiencing the American dream.
I've had the Corvette previously and enjoyed it immensely (nearly got into a lot of trouble too after I was stopped for doing 117mph in Death Valley!) - thought I'd try the Camaro and Challenger this time for variation.
Sorry OP, totally O/T as I feel the State may be a bit far for your flight limitations!
