CONCORD, N.C. -- There was a special guest on the Hendrick Motorsports campus Tuesday afternoon.
Molly Quinn, one of the stars of ABC's Castle, toured the race shops.
"I'm a big car fan," she said as she walked around the Nos. 5/24 race shop, "and got a suggestion from a good family friend that this was the place to go."
Quinn, who has also appeared in several movies including 2013's We're the Millers, said the size of the Hendrick Motorsports campus was impressive, but that wasn't the part of the tour that surprised her the most.
"I don't know if I was surprised -- I was very open-minded when we came here," she said. "But I was surprised at how clean everything is. It's really spotless."
The actress said she enjoyed the chance to get an inside look at Hendrick Motorsports.
"I've had a great time," she said. "It's been great."
