When I bought my car several years ago, the cigar lighter was also missing. The female plug in was there,all corroded, but the lighter was gone. I just went to Auto Zone, and bought an after market one that has the light in it with a green plastic ring around it that I connected to my headlight circuit so that it is illuminated at night. Works great, looks OK.
I have after market Sparco seats, and a lot of none-stock items on the car already, so I wasn't too concerned about an original lighter. Just wanted something that looked good and an outlet that worked to charge my cell phone.
If you don't care wether its an original piece, most any after market lighter will work.
Hope this helps.
