Step Daughter problems (need advise)

I have a 19 year old step daughter thats disrespectful, unmotivated, lazy, no job, and a compulsive liar. I kicked her out the house once and she was gone for adout 8 months. She went to live with her aunt and got kicked out of there after a few months, and then stayed with a few different friends and got kicked out of there also. Now she is back home and its the same old **** again, she thinks she can just run the streets all day and night and come home to shower and change clothes. I've done nothing but tried to help her. I bought her 2 cars and shes done nothing but completely trashed them. Every panel scratched up and dented even the roof and burn marks all over the interior, and there now both in the scrap yard. I'm to my last nerve here and want some advise on what to do. As of right now I'm waiting until it gets a little warmer so I can kick her *** to the curb. But would like everyones opinion on the matter.
PLEASE HELP
