D'Angelo Russellwent joyriding in a luxury whip before signing his massive, $117 million deal with the Warriors ... taking a crazy expensive Ferrari out for brunch ... and TMZ Sports has the vid!!
Just hours before inking his reported 4-year deal with the Dubs on Sunday, DLo hit up Toast Bakery in L.A. with his folks ... and the dude knew how to make an exit, hopping in the passenger seat of the Rari and riding off down the street.
We fired off a bunch of questions -- if he had a message for the Brooklyn Nets after dealing him to the Dubs, if he's the newest Splash Brother, if the Warriors were still the team to beat in the NBA ... but the All-Star guard let the wheels do the talking.
No word on the exact year and type of this particular Ferrari ... but given the price tag of similar models, it's gotta be worth a quarter million dollars AT LEAST.
