Hey, Zac Efron—we're free for a spin! 

The Dirty Grandpa star revealed his finished, restored 1965 Ford Mustang on Instagram, Monday. 

The car, which originally belonged to "Grandpa Efron," took two years to refurbish, according to the actor. 

With a shiny gray exterior, the vehicle is a convertible and features silver rims and what looks like leather interiors. 

In one photo, Efron, wearing sweatpants and red sneakers, sat on the back of the car. 

"After 2 years of remodeling, my grandpa's 1965 Mustang is finally ready," Efron wrote. "It's a beast." 

He posted several more up-close images of the sweet ride including one as he zoomed off with a special passenger—girlfriend Sami Miro.
