I put a lot of work into building types files and market files for an upcoming server and it didn't feel right to hoard them: https://github.com/omniomi/dayz-rusforma_vehicles-files/.

I used scripts that I wrote to parse out the vehicle and part names from the PBOs directly, parsed out the attachments and default parts (truck vs. car battery, spark vs glow plug, etc,) and parsed out all of the variants of each. I used those lists to programmatically build the xml and json files so they are as complete and accurate as humanly possible.

Note on setup: the types files are setup to not spawn anything in the environment and the trader files have default prices for everything. Some tweaking is still necessary.

Note on categories: I split the market files for the vehicles into cars, trucks & jeeps, vans & busses, and military. You may want to rearrange some of them as there's a lot of jeeps that are technically military jeeps and so on. I leave the final categorisation to you.
