John Cena has a hobby of collecting vintage cars. Nikki Bella once had a separate section in her Youtube channel to showcase some of those beauties from his garage. These include 1970 Pontiac GTO, Ram F4, etc, and over 20 muscle cars alongside a Ford. In an interview with Men’s Fitness, he confessed to spending spare times with these vehicles.
