Yes DCED is very crashy.You need to be very careful working with that.
As you can see there are not exact models in that window there are just names like polimTud which tells it to add exact model which is registered under "polimTud" for example.
Its made like that because of different colors of the cars.So you just add for example "card_ford" and it will add cars like that to freeride with different colors because one model of 1 car has only 1 color obviously.
So you must find a mission where that car is and add that name in there.If there is not a car like that anywhere there should be a way how to do it but i cant give you a tutorial as i have never done this..
