Car crash with bumper and shock spring

Hi Team,

I want to simulate like in video with SOLIDWORKS motion: Car crash with bumper and shock spring | SolidWORKS 2017 Assembly | Motion Animation Tutorial - YouTube 

I want to simulate the bumper touching the base part, the car will stop like in the video.

I setup contact between bumper& base but the car doesn't stop after bumper touching the base part. The car continues to move and interfere with the base part.

I have attached file, pls help me recoment I need setup contact is correct.

Thanks
