John Cena – 1970 Plymouth Superbird, $500K

That may be a staggering price to pay for one car but considering John Cena’s net worth, one shouldn’t be so surprised. In fact, this isn’t the most expensive in the muscle man’s collection of over 20 muscle cars. He is also known for his InCENArator, which is truly a millionaire’s toy. A custom-concept car, it has eight exhaust pipes that shoot out flames! It used to be a Corvette which John had transformed to a year 3000 car – that was his specific instruction.
