Item description:

Also here is a link for a save file with 82% collectables done. You can cross out the ones collected in this save (check in the pause menu) from the guide -

powerpyx.com/mafia-1-remake-definitive-edition-collectibles-guide/

and go for the rest to obtain Lending Library, Picture Book Connoisseur, Full set, Car Thief number One, Mystery Fox Domination, The Whole story, Motor Museum.
Note that since its 82 percent complete trophies like Quite the collection (Collect 15 cars) and On the trail ( collect one hidden car ) are already done so they might NOT be possible with this save, but the rest should work.
