Car sales men, or people who know about cars with leases?

[Fatty]

I leased a car about 3 years ago...only 30000 mile for 3 years, now I find out bad idea I have 43000 and four months to go. I know I can buy it for 9000,witch I have already paid that amount in the lease. So now i am paying double. the amount of the car..oh yeah its a 2007 ford focus. What would be my best option to pay for the over miles, buy it so i have a car, or what I have no clue. I got rip off with the lease and would like to fig out the next best thing to do. Thanks for the help
