Right behind the glass doors of a busy dealership, a jaw-dropping collection of legendary race cars is just sitting there, waiting to whisper sweet, horsepower-laden nothings into your ear. The Penske Racing Museum sits within the Scottsdale 101 Auto Collection at 7191 E. Chauncey Lane in Phoenix, Arizona, sharing space with showrooms for Porsche, BMW, Ferrari, and Lamborghini. The contrast between brand-new showroom vehicles and battle-tested race cars creates a genuinely fascinating atmosphere. The Rotating Collection Of Historic Race CarsAround 15 to 18 race cars are on display at any given time inside the museum, but that number only scratches the surface. The second floor of the Penske Racing Museum houses one of the most visually striking trophy displays you will ever encounter outside of a professional sports hall of fame.
