i would like to sell my car

If you didn't transfer the title and registration to your new location it's not a problem. You can sell the vehicle without doing anything with the title and registration. Show any prospective buyers your driver's license to prove you are who you say you are and that you own the vehicle. When filling out the back of the title for the new owner, put your OLD address, driver's license number, etc. exactly as it appears on the front of the title, and you'll be fine. Hope that helps! Jim
