It doesn't matter if you finished Need for Speed Undercover or not.
Do you want to unlock all the cars (and more) in the game ?

If the answer is yes, you just have to go here :
LINK : https://mega .nz/#!2EMwgTqb!Ma94bhL6PcqB_r1Dx7-qmzCVXgcp4j-ypnqkiYwD73E

Download the save, unzip the file and paste it "\Documents\NFS Undercover"

Example : C:\Users\AymericTheNightmare\Documents\NFS Undercover\AymSpec

Run the game, and load the "AymSpec" save. Now you have all the cars in the game plus the city cars (trucks, police, etc) !
