I've seen a lot of people in the past wanting an updated vehicleData.json and no one posted an updated version.
There is also a script posted here somewhere on the forums that is supposed to generate an updated version of this json, but it doesn't works because the script is generating data from server-side API which gets data from the json... so it's a json loop, it creates a new json with what's on the current json file you have.
This one is generated by me, using my own client-side script which actually gets data from natives, it was tested and works (it has all the available vehicles from wiki):
