DiRT Rally Possible way to mod in new cars?

[RaptorInMotion]

I've found a new place by accident that has these perfect looking car models that come in all kinds of formats.

Now I don't know about modding at all but is it possible to replace a car with these models? Specifically the Yaris

I'd happily pay for it.

The cheapest at $3k for one model of the lowest quality is a no go for me and probably nearly all of the sim community!
