Hello there,
I am specific good at the running of new models data base. ( https://github.com/Fernando-A-Rocha/mta-add-models ) It is a data base allows you to create unlimited vehicle, skins and objects. With this resources, I mostly work on handling and making it work with scripts ( such as a buy car script ) and models ( change dff and txd files ).
