When I first played the original 2002 Mafia game I was not only intrigued with the story and the history of crime families, but also the cars. When the remake came out this year, and they brought back those cars, they looked hot, unique and rather sophisticated due to my passion for vintage cars of the 1930's time period. It would even better if someone or a modding team had those cars created as add-on mods to GTA 5, then those players can customize their colors and keep those cars to themselves on their own copy of the game. It is understandable that it will take time to covert those cars over to GTA 5. However, I do hope that creating these mods over from Mafia: Definitive Edition to GTA 5 will be a possibility and come into furition in the future.

Very good request, but question is, where are they going to put it to avoid conflict with the North Yankton, Liberty City and Vice City DLC Add Ons?

I wish there were formal winter clothing such as overcoats available to Micheal and Trevor in the form of an add on clothing mod without interfering with the original clothing files like the current Trench Coat Pack mod for Micheal currently does. When I open up simple trainer and go into add on clothes, I should be able to see it as a selection on the add on list and once clicked I want to see him purely in those add on clothes without overlapping of the original clothing files, editable on Open IV.

I have the same problem except that when I play in Vanilla, I can gain access to Micheal's house without crashing. Every time I have the game modded when I approach Micheal's house, it crash no matter if I get rid of a script mod or two, it doesn't work. Is there any solution to this? I use a Steam version of the game using a modded launcher. I never modded any rpf files so far.

Do you know how to add it on manually or not?

I wish that this mod would be able to work with the Liberty City Rewind Mod, The Vice City mod and the North Yankon mod. In addition I wish there was a way for the game to recognize certain boroughs of LC (like Westdyke and North Holland) and VC (like Little Havana and Little Haiti) without calling the expansions the Pacific Ocean. No one will tell if this would happen.

@Willief23 The problem with gameconfigs is not that only the story mode missions don't work, but side missions (Strangers and Freaks and Property Missions) as well; in addition to hangouts, for example when I try to play darts with a friend or try to play golf nothing happens. What I want to know is. Does your gameconfig solve any of those problems? If not, is there any way to solve them?

@Sonnenfalke I had created a shortcut on the desktop, but it keeps creating a no launch error.

In case of confusion, some images of vintage cars may clarify what specific cars I have requested for the pack or mod.

It would be great if someone replied to this request. Thanks.
