FiveM vehicle packs and single car models for roleplay servers: sports and luxury cars, tuner and widebody builds, and emergency fleets such as unmarked police packs, marked patrol cars and a police helicopter.
Vehicles are streamed assets, not scripts, so they do not need ESX, QBCore or QBOX. Check the product page for whether a model is an add-on or a replace, how many vehicles a pack contains, and whether liveries, tuning parts and a handling entry are included. Add-on vehicles also need entries in your spawn list or dealership script before players can get to them.
Compare screenshots for interior detail rather than exterior renders, and check the file size against your stream budget. Free vehicle downloads are collected separately under free FiveM cars.
