Info
We've all been through this, you started working on your FiveM server and started adding vehicles, but, you got tired of switching back and forth between OpenIV and 100 notepads open. I made this tool for you.

System Requirements

• Microsoft .NET Framework 4.8 https://dotnet.microsoft.com/download/dotnet-framework/net48

How to use

• Firstly, make a list of the vehicles you want to add.
• You must search for (AddOn/Replace) vehicles. Click the first download button and then right click the second one (if it's there) and hit Copy link address. I'm attaching a GIF to help you. 
• You must copy the DIRECT link, else the script won't work!
• The link must look something like this:
• https://files.gta5-mods.com/uploads/xxxxxxxxxxxx/yyyyyyyyyyyyyy.zip
• If the link looks like this you've done something wrong:
• https://www.gta5-mods.com/vehicles/2009-acura-tl-replace
• Run the executable (no admin privileges needed)
• Add a link and change resource name to your liking, or don't change anything for random numbers.
• Wait for the program to unpack and do everything for you.
• You're done!
