The Shelby GT 500 KR One of the things that Russ loved most was cars. He had a special place in his heart for the Shelby GT 500 KR, which he nicknamed "The Heart of Gold." This car was a symbol of his love for cars and his passion for life. When Russ passed away, he left me "The Heart of Gold." I knew that I had to do something special with this car to honor his memory. I decided to build a museum around the car and turn it into a Hot Wheels car museum.
