Your best bet is to check the Yellow Pages for "Car Rentals" and "Limo Rentals". Some local companies have what they call exotic vehicles to rent for parties, weddings, etc., and the Dodge Challenger SRT8 may be in stock. Metropolitan areas would be your best bet, so if you are travelling to Las Vegas, NYC, Phoenix, etc. in the near future, try to check there ahead of time to reserve it. Good luck!
