Issue was me being newbie. I didn't know they won't show up directly in police garage. You have to use F4 console or TrainerV, although I didn't use the latter yet.
F4 and in console type: spawn camp
In the file description you have a list of all cars and their codes
In general, awesome pack.
Can you actually prove this accusation? I have my PC with very restrictive firewall rules and haven't seen any indication (in monitor or warning) that it would ask any credentials/data going out of my PC.
I followed the instruction for full install with crosschecking each step three times but can't load the vehicles at all. They do not appear in game.
If someone can help me with that, I will be thankful.
