I have been trying to track down a 260 Z that I bought new in 1974 and sold in 1978 .The web sites I have been using indicate that the number is invalid . I have the original window sticker and it shows Serial No RLS30-018365 ,not a Vin # as we know it today . Any sugestions on possibly finding this car if it hasn't already been crushed. I'm just curious to see if it is still around.
