I have never done an add on vehicle yet but would like to.  The vehicles I have now are all replacements.  I like those because their quick and easy to put in but when a big update happens like the last R* I couldn't start the game and found it was due to the mods folder being messed up after the update.  I heard on add ons those aren't affected by updates because they are installed in other areas.  That True?  What vehicles types do you prefer to install, replace or add?  Also can you change a vehicle that is meant for replace to an add on?  I have this one vehicle that is to replace police slot but it's a HP vehicle and I want it as an add on.  I want the police 1-4 to stay city PD but the HP vehicle I have is for the police slot.  Wondering if that can be changed. 

I believe there is a way to "update" your mods folder after a major patch without having to remove your addon vehicles. I personally prefer addons, but the way I go about it takes a lot of work and isnt the fastest way. For me, I prefer to use the addon method for plane, helicopters, and civilian vehicles. As far as I know, you cannot change a replace to an addon, but I could be wrong. If you want the Highway patrol to be for the Highway patrol slot, I would recommend finding another vehicle that is addon. There could be more info that could be added to this discussion, so if anyone else has any additional comments that would be fantastic!  

Ok.  Yeah, with the last update I just deleted the mods folder and made a new one.  Copied the new Update and X64 into it with X64C and E because a couple of my mods needs those files.  Took some time but I eventually reinstalled the 6 or 7 so mods ,not including vehicles.  I don't know how to update the mod folder.  Maybe can you copy paste the update and x64 from the main into your mods?  Actually I know you could do that but will it delete the mod files since those weren't in the original?  Maybe I'll try it next time on a big update. 

 

Unfortunately that vehicle I have is a CHP Dodge Monaco 75(?) from SOLO.  The files goes into the police1 slot.  I can't find any other CHP Monaco.  I could still use it but it would spawn in the city.  If I can't change it then oh well.  I almost thought I saw somewhere instructions to convert replace files to add ons and it was a lot of steps.  I'll look around some more. 

 

The policeb slot is for the only police motorcycle which usually spawns on the freeway and has an HP officer on it.  I actually have the Hurk's CHP BMW cycle in that slot.  I don't mind the motorcycle police even though they don't last long in pursuits, I kinda laugh when they bite it.  If I were to add the b at the end of the files I don't think the handling would be right since it is a handling for a bike not a car.  Unless I could change the policeb handling to some other car.  Just thinking out loud here.
