Reason:

These cars are missing from Legacy and PDM. I think they could be added as better versions of the base model cars for an increased price as they are racecar variants of the stock ones

I created a development command to create lists that categorize every spawnable vehicle into 3 categories: native used, native unused & add-on. 'Native unused' having the ones that are in the base-game but not used in PDM. Could be useful if @joevapes3 (or someone else) would like to price and add more vehicles into PDM.

Here's a link from a list created today.
