20K first gen Lotus Cortina,,,, yeah,, you keep dreaming that dream. i am sure i can find you one, so long as you so not want it running, or rust free, in one piece,, etc.
Perhaps you should start thinking A.L.F.A. , Fast B-sedan / Trans-am cars of the era, not named DATSUN .( if you are feeling really gullible , i have a Pinto with your name on it! )
