The idea behind is fine for people with HIGH END PCs but that streaming MiBs consumption is real high, the very last row in resmon.
That is with GTA vanilla cars, imagine if those cars were addons.
And another idea, in the sync video the teleporting is really ugly, not going to lie, you should work on that and make it so people can actually drive off with vehicles.
An idea is to add a decor on the player that first entered the garage and then make it so he becomes the entity owner of the vehicles so that way you don’t duplicate them on other clients.
You could take a look at what he’s done: [Release][OneSync] Enc0ded Persistent Vehicles
Other than that, I love vehicle releases and this looks nice, but you should really take those advices and make this a better script and lower the price, you’ll get more sales and it’ll be better for you when MORE people have it.
