Arnold Schwarzenegger and Sylvester Stallone are Hollywood legends who have been in the movie scene for nearly fifty years. The two iconic action heroes were the best in their heyday, pulling off breathtaking stunts and gun control. But as they rose to prominence in the '80s, rivalry ensued between them, and it lasted for close to two decades.

While Arnold and Sly may see each other as on-screen competition, we will focus on who has a better garage. With both actors having a net worth of over $400 million, they have held nothing back when it came to lining their garage with some of the most exotic and expensive cars on the planet. Stallone and Schwarzenegger's car collections say a thing or two about their personalities, but they also show who's the bigger gearhead.
