Over here in North America they are not called Sprinter Trueno or Levin. I think this is because Ford had already released a car over here called a Trueno. So over here they are just Corollas. The model you are looking for is a 1985-1987 Corolla GT-S. Do NOT get an SR5 as they do not have the 4A-GE engine.
You can look on ebay which was already mentioned. You can also check the auto trader web site. Look in our for sale forum as well as the Club 4Ag web forums for sale section (
www.club4ag.com ). Also check your local news papers from time to time (that is how I found my first).
