It's almost certainly mostly CGI but even if it was done with practical props, they are still not "real good objects." They are props. No one crashes real Ferraris in an action movie. You use fakes and empty chassis.
They do crash real cars in movies though. The Wolf of Wall Street saw an actual Lamborghini Countach with a VIN get crashed quite a lot, John Carpenter's Christine went through like twenty Plymouths and The Dukes of Hazzard TV series destroyed hundreds of cars ("an estimated 309 Chargers were used").
