As long as you don't then engage in fraud (e.g., attempt to get reimbursed by car insurance for the damage), harm or endanger anyone else in the process, or otherwise violate the law you are free to do as you please.
It's legal to damage or destroy your own paid-for car, including breaking the windows. You just can't do it in a way that's illegal, such as by burning it (which could be considered arson).
If someone tries to stop you and lays their hands on your first, you have the right to defend yourself, which includes pushing them away.
