Need help installing a vehicle:)

I need help I wanna install a vehicle but it has a xml file instead of a dlc how would I do that

These vehicles are probably ELS based. If you are running a non-ELS server, you must download non-ELS files and vice versa with an ELS server.

A tutorial that may help you:

It’s just one xml file there no other files it’s a sofa car

Do you mind linking me the post that you got this car from? (If you can.)

Here ya go
