Welcome to GTA5-Mods.com

I use this mod primarily because I fly in this game a lot. So it prevents the car I drive from respawning. You can find really cool garage expansions in the 'Maps" tab of the website. However, I agree in the fact that OP should add a feature where the saved vehicle is repaired overtime, like the safehouse garages.

@kithylin You can save across all three characters, however, if you find the blips disappearing, just press by default NumPad 0. This re-loads the saved vehicles. As for repair, any Trainer will do the job.

I love the mod, however, the only issue I've encountered thus far is that every time I exit the game, then play it again, a duplicate of the vehicle I've saved is created. Is there any fix for this? Much appreciated.
