Now there are no more relationships to other tables, because i deleted 
all localization fields.

What do you mean exactly with model definition? Maybe I missed something.

Inside Classes/Domain/Model there are my Models (Car.php etc.)
The tables are named tx_autoadmin_domain_model_car etc

Do I have to activate/assign the models somehow or will these Classes be 
discovered automatically by naming conventions?
