Not able to get more vehicles ? – Construction Simulator 2 Review

Hi I had a question about get new vehicles because I am almost at level 10 and still can’t get any other vehicles from the ‘vehicle bay or park’ and can’t accept any jobs because I don’t have the equipment yet for it. Could somebody tell me how to fix it. It would be much appreciated! ? thank you!
